SBNews: News Robot Utility (C) Scott M Baker ------------------------------------------------------------------------------- I variously refer to this program under the names "NewsBot" and "SBNews" throughout the document. You can for the most part consider them to be the same. Eventually, I plan on including extra utilities in this package, "SBNews" will be the name of the full package and "NewsBot" will be the name of the News Robot utility within the package. ------------------------------------------------------------------------------- Table of Contents * Purpose * General Information * System Requirements * Distribution Information * Features * Files Included * Installation * Command Line Parameters * JPEG Viewer * Configuration * Appearance * Host Name * Download Path * Path Expansion * Miscellaneous * Lockout Lists * Authentication * Acceptable File Masks * Dupe Checking * AutoSave * Auto Encryption * Files.BBS Generation * Statistics * Coord: The Newsbot Coordinator * Unfinished Stuff/Planned Enhancements * Acknowledgements * Registration * How to Contact the Author * Revision History ------------------------------------------------------------------------------- Purpose: The purpose of this program is to automatically download and uudecode files from newsgroups via a winsock connection. If you've found this program, then you probably know what this means, so I won't go into detail. Newsbot will attempt to piece together multi-part files. If you're new to binary newsgroups, then here are a few G-rated newsgroups that you might wish to try: alt.binaries.pictures.astro alt.binaries.pictures.animals alt.binaries.pictures.cartoons alt.binaries.pictures.fractals There are a wealth of adult-oriented newsgroups, but I'm not going to list them in this document. I have included a sample file, SAMPLE_G.TXT, which includes a listing of binary newsgroups. There are no descriptions, but you can probably find out from the newsgroup name what subject matter the newsgroup deals with. ------------------------------------------------------------------------------- Requirements: * Windows 3.1 or greater * Winsock connection capability (i.e. SLIP or PPP) Distribution: * 16-bit (Windows 3.1) Version: SBNEWSxx.ZIP (xx denotes version number) * 32-bit (Windows 95) Version: SBN32_xx.ZIP (xx denotes version number Features: * Unattended download - do other work (or go out to lunch) while downloads and uudecoding are all processed for you! * Automatic HTTP address logging -- NewsBot will keep track of any HTTP URL's that were found while downloading addresses. These will be saved to a convenient HTM file, HTTPGRAB.HTM. * Built in JPEG viewer. Allows you to see postage-stamp size images of the files you are downloading in progress. * Delete/View previously downloaded JPEG files. * Comprehensive logging capabilities - save the subject and from information for files that you might want to follow up on later. * Dupe Checkers -- avoid downloading the same files multiple times. * Auto-Encryption -- can be set to automatically encrypt files when saving to disk to keep their contents private. * Automatic FILES.BBS generation for sysops * Eliminate advertisements/SPAM with the Maximum XRef Limit (see preferences) and the XRef Lockout Filter (see lockout lists) Files Included: * NEWSBOT.EXE: Executable; what you need to run to get the program to work. * NEWSBOT.HTM: Documentation in HTML format (read with your browser) * NEWSBOT.DOC: Documentation in plain-ASCII format (read with any plain ascii text editor) * BWCC.DLL (16-bit) or BWCC32.DLL (32-bit): Borlands Custom-Control DLL library; used to support Newsbot's grey dialog boxes. * FILE_ID.DIZ: Brief description file; useful for bbs distribution * SAMPLE_G.TXT: Plain-ASCII listing of binary newsgroups * REGISTER.HTM: Registration info in HTML format * REGISTER.DOC: Registration info in plain-ASCII format * README.1ST: General information on documentation & archives * ENCRYPT.EXE: Standalone utility, Used to encrypt files on disk * DECRYPT.EXE: Standalone utility, Used to decrypt files on disk * COORD.EXE: (32-bit version only) Used to coordinate multiple Newsbot applications running concurrently ------------------------------------------------------------------------------- Installing and Using the Program: Here are some very quick notes on installing and using Newsbot: Installation: 1. Unzip the distribution archive into the directory of your choice. Running: 1. Run NEWSBOT.EXE -- this can be done in various ways - from the Win-95 command prompt, the Windows Explorer (and/or file manager), the Windows Run Program command, etc. 2. On your first session, you'll be prompted for a "News Host Name". This is the name of your news host, and should be given to you by your ISP (internet service provider). 3. On your first session, you'll be prompted for a "download path". This is the path where you want the files you download to be placed. 4. Once NewsBot is loaded, you'll want to add some newsgroups. This is done with the "Add" button. You'll need to know the names of the groups you want; you might want to consult SAMPLE_G.TXT for some sample newsgroup names. 5. Press the "CONNECT" button to start everything. All else should be mostly automatic from here on. Feel free to tinker around with the menu items ------------------------------------------------------------------------------- Command Line Parameters * "-i INI_FILE_NAME". Sets the name of the INI file to use. By default, newsbot uses the file newsbot.ini in your windows directory. Specifying a filename here will cause newsbot to use the file under that name in newsbot's home directory. For example "Newsbot -i news1.ini" would use the filename "news1.ini" in newsbot's home directory. * "-auto". Will automatically begin downloading news articles as soon as newsbot has loaded. Note: For unregistered users, about screen will still be displayed! * "-autoexit""-noabout". Omits display of the about dialog on startup of Newsbot. Note: Only supported in registered version! ------------------------------------------------------------------------------- Jpeg Viewer SBNews has a built in Jpeg viewer for viewing JPEG files offline. The JPEG viewer can be operated in several ways: 1. By double-clicking on a [RECEIVED] entry in Newsbot's log window 2. By single-clicking on one of the preview pictures on the right hand side of Newsbot's main window. 3. By using the FILE:VIEW JPEG option from Newsbot's pulldown menu. Once loaded, the JPEG viewer window will display the JPG file selected and include a listing of filenames and directories on the left-hand side of the window. This listing is provided to let you easilly select other files to view. Double clicking on a directory in the directory list will change to that directory and double clicking on a filename in the file list will display that file. The CHDIR and VIEW buttons perform the same functions, respectively. The "<" and ">" buttons will view the immediately previous and next files in the currently selected directory. You may use these to rapidly view a list of files that were downloaded overnight for example. The ">" button will activate a slideshow of the current directory. Each file will be displayed, there will be a slight delay, and the next file will be displayed. The FILE menu of the viewer has several options: * Open File: Allows you to open a new file using the windows common-dialog open method. * Delete File: Deletes the current file that you are viewing. * Save as BMP: Saves the current image as a BMP image, which may later be used as windows wallpaper, for example. * Set as Wallpaper: Saves the current file as a BMP and tells window to use it was wallpaper. The SlideShow menu has a few options as well: * Start/Stop: Starts and stops the slideshow, equivalent to the ">" button. * Set Interval: Sets the amount of delay between slideshow pictures. * "Normal Mode": Images will be displayed in the jpeg viewers window. * "Wallpaper Mode": Images will also be set as WallPaper. This sort-of turns your entire desktop into a slideshow display. You can minimize the JPEG viewer window and continue to do work while images display in the background as wallpaper. ------------------------------------------------------------------------------- Configuration Appearance: Newsbot has several different main window styles. You may select whichever style appeals to you most, they all convey more or less the same information: * Small: Designed to display as much information as possible in a small footprint. The "file log" is unavailable, but all other information in present. * Large: Default configuration for systems with 800x600 resolution or above. * Windows-95 Tabbed: Same footprint as the small dialog, but uses a tab control to select different panels of information. Somewhat less cluttered, but you will need to use the tab between the information you want to see. Large current/previous thumbnails. Host Name: The host name is the name of the nntp host which NewsBot will connect to. If you don't already know this, then you may wish to contact your Internet Service Provider (ISP) or check an existing news program on your system for the name. Download Path: The base path where downloaded files will be placed. If you enable any of the download path expansion (see misc. preferences), then files may be downloaded into sub-directories of this base path. Path Expansion: By default, all files will be downloaded into the download directory that you have specified. However, this can lead to confusion, since you will not know which files came from which newsgroups. Thus, there are several "path expansion" options that will create a sub-directory tree for the individual groups. The options are: * None: All files go into the same subdirectory * Group Number: Files are placed in numerical directories, according to their order in your newsgroup list. * Expanded Group Name: Each field of the Newsgroup name is made into a subdirectory name. For example, "alt.binaries.pictures.misc" would become "alt\binaries\pictures\misc". This option is useful for Windows-3.1 systems, since subdirectory names may only be a short length. * Full Group Name: The entire Newsgroup name is used as one big subdirectory name. This is only available in Windows-95 with long filename support. ┌──────────────────┬─────────────────────────────────────────┐ │Path Expansion Exa│Resultant Path es.pictures.misc) │ │Path Exp Setting │ │ ├──────────────────┼─────────────────────────────────────────┤ │None │c:\download\ │ ├──────────────────┼─────────────────────────────────────────┤ │Group Number │c:\download\group1\ │ ├──────────────────┼─────────────────────────────────────────┤ │Exp Group Name │c:\download\alt\binaries\pictures\misc\ │ ├──────────────────┼─────────────────────────────────────────┤ │Full Group Name │c:\download\alt.binaries.pictures.misc\ │ └──────────────────┴─────────────────────────────────────────┘ For the "group name" options, you may wish to trim repetitive prefixes from the front of the path name. For example, there's no need to include "alt.binaries.pictures" in the beginning of each pathname -- it just leads to wasted space. The Path Prefix Removalbox is used for this purpose. Any string(s) that you enter in this box will be removed from the front of the newsgroup name before the path is generated. Miscellaneous Preferences: Miscellaneous preference options are located under the Configure menu under the heading Preferences. * Logging: Logging options control the creation of the newsbot.log file. The log may be useful so that you have more information about the files that you have downloaded. The log filename is "newsMMDD.log", where MM is the current month and DD is the current day. For example, the log for June 6 would be saved in "news0606.log". The log is plain-ascii and may be viewed with any text editor, or by using the dos "type" command. * Log Enabled: if checked, then a log file will be written. Otherwise, no log will be written. * From user name: records the name of the person who posted the message * Subject: records the subject line of the message * Comments: records the first few non-file lines of the message. Useful if the sender has prefaced the message with some explanation of it's content. * Too Small: Messages that are below the minimum message line limit (see below). * Too Long: Messages that are above the maximum message line limit (see below). * Dupe File: Files caught by the dupe-file checker. * Dupe Subject: Messages caught by the dupe-subject checker. * Mime Headers: Really just debugging info for me.... * Delete old Logs: If checked, then any log files not equal to the current date will be deleted when newsbot is run. This minimizes * Case Conversion: These options will convert the case of the filename to a uniform format. Due to limitations in the 16-bit application model, filenames will probably be always upper case in the 16-bit executable. * None: Leave filename case as it appears over the modem. * Lower: Convert all filenames to lower case. * Upper: Convert all filenames to upper case. * Disconnect/Reconnect: The disconnect/reconnect system will automatically disconnect and reconnect the current nntp session in order to abort a message that is being transmitted. This is used to save time, rather than downloading entire messages which are not stored on disk. If you disable disconnect/reconnect, then Newsbot will receive the entire message, although the message will not be written to disk. You may toggle disconnect/reconnect on or off for several subcases: * No-Data: Messages with more non-encoded lines than the no-data threshold set below. * Dupe-File: Files caught by the dupe-file checker (not relevent to the dupe-subject checker, as the dupe-subject checker won't download the message in the first place) * No-Mask: Files which do not match an acceptable file mask. * Current-Delete: Files which were deleted during transfer by a user request. * Lockout-File: Files whose names are matched by the lockout filename system. * Lockout-XRef: Messages where a string in the XRef field matches the lockout-xref system. * Lockout-Host: Messages where the NNTP-Posting-Host name matches the lockout-host system. Note: Sometimes the Disconnect/Reconnect options may cause your news server to record an excessive load. This is because Newsbot will disconnect the connection, but your news server may continue to keep the connection open for a short period of time. Thus, the news server may think that you are using more connections than you really are. This situation is unlikely, but if it does present a problem, then you may wish to disable the disconnect/reconnect options. * Message Line Limits: Newsbot can limit which messages are downloaded based on the length (number of lines) of the message. * Minimum Lines: Messages with fewer than the specified number of lines will not be downloaded. The rationale is that small messages do not contain any useful information (pictures are big!) and some efficiency may be obtained by not downloading them. * Maximum Lines: Messages with greater than the specified number of lines will not be downloaded. The rationale is that really huge messages are a waste of time. It's usually the case of someone who scanned in a picture at too fine a resolution. * "No Data" Threshold: This specifies the number of lines that can be in a message when no attached files (eg images) can be found before the message is skipped. For example, if 500 lines are scanned, and no attached image is present, then the message is probably grunged, a misplaced part of a multipart encode, or some other useless data. * Maximum XRef Limit: Many people have complained about an excess of off-topic advertisement messages (i.e. SPAM) being present in the newsgroups. This option is designed in an attempt to avoid these advertisements. Typically, advertisers will post their messages to a large number of newsgroups, and thus the XREF list for the article will have many entries. Newsbot can be set to filter messages with too many XREF's out. The default is set at 999 which effectively disables XREF filtering. You can enable XREF filtering by entering a lower number here (10 is a good place to start). * Preload XRef hdrs: By default, the "lockout XRef" and "Maximum XRef Limit" systems do not filter out an invalid message until the download has begun. This is because the XREF line is not transmitted until the message is sent. However, you can tell Newsbot to download all the XREF headers ahead of time, before any messages are downloaded. Thus, Newsbot will know the XRef information ahead of time and can avoid the unwanted messages entirely. However, XRef information is somewhat bulky, and does require a fair amount of time to download the headers. Thus, there is a trade-off involved. Feel free to experiment. Lockout Lists: The lockout lists are used to lock out messages that contain certain text strings. For example, you may not wish to download messages written by a certain person, or messages whose title contains a certain string. There are several types of lockout lists supported: * Lockout Poster (i.e. Author): Applies to the "From:" line of the nntp message. Use this if you wish not to receive messages from a specific person. * Lockout Subject: Applies to the "Subject:" line of the news message. This is useful if there are certain keywords which you want to lockout if they are present in the subject field. * Lockout FileName: Prevents specific filenames from being downloaded. You can type a specific filename or a wildcard specification to lockout a group of files. * Lockout Host: Checks the "NNTP-Posting-Host" field of the news message. This is useful to eliminate posts from a specific news server. Many obnoxious posters will alter their email name in the from field, making them impossible to lockout by normal means. However, the news server usually will put it's correct host name in the "NNTP-Posting-Host". Thus, this field may be used to weed out the obnoxious poster. However, be warned that locking out a NNTP-Posting-Host will lockout all users who post from that host! * Lockout XRef: Checks the "XRef " field of the news message. The XRef field contains a list of other newsgroups that the message is cross-posted in. Sometimes a person will post a message into several groups at once -- this is called crossposting. Sometimes an obnoxious poster will cross-post their messages into groups that they don't belong in. All lockout lists are case insensitive (i.e. capitalization does not matter). All lockout lists support wildcard characters, * and ?. "*" is interpreted as "any sequence of zero or more characters" and "?" is interpreted as "any single character". Here are a few sample wildcard strings: * (Lockout-Poster) "joe@fubar.com" would refuse any messages from joe@fubar.com * (Lockout-Poster) "*@foobar.com" would refuse messages from ANYONE at fubar.com * (Lockout-Poster) "joe@*" would refuse messages from "joe" no matter where he posts from * (Lockout-Filename) "*.zip" would refuse any file that had an extention of ZIP * (Lockout-Filename) "fastcash*.*" would refuse any file which had "fastcash" as the first 8 characters. * (Lockout-Filename) "index-?.jpg" would refuse any file which had "index-", exactly one more character, and then ".jpg" as an extention. * (Lockout-Host) "news.somehost.com" would refuse any messages posted on "news.somehost.com" * (Lockout-XRef) "alt.binaries.pictures.erotica" would refuse any messages that are cross-posted into "alt.binaries.pictures.erotica" The is an additional toggle which lets you toggle between an "exact match" and "match any position in text". * Exact-Match: The search pattern must match all of the text exactly; There can be no leading or trailing characters. For example, "abc" would not match "abcd" or "xabc". * Match-Any-Position: The search pattern can match any position in the text. There can be leading or trailing characters. For example, "abc" would match "abcd" and "xabc". There is a TEST button on the lockout dialog which will let you enter a string and see if it matches anything. This is useful if your a little confused about the wildcard strings and want to make sure what you entered does actually do what you think it should. Note #1: The "NNTP-Posting-Host" and "XRef" lines of a message are not normally displayed by SBNews, so you might be wondering where to get the information to type into those lockout lists. If you notice a particularly annoying message, you can use the Headers button to bring up a header listing for the group, then use the Read button to display the full text of the annoying message. Inside the read screen will be a header listing where you can find NNTP-Posting-Host and XRef fields. Note #2: Some lockout settings, such as Lockout Poster and Lockout Subject can be determined before the message is downloaded. Thus, Newsbot will bypass the message completely. Others, such as Lockout File, Lockout Host, and Lockout XRef, can not be determined until the message has begun to be received. Thus, Newsbot must start receiving the message and then abort the message while the download is in progress. Authentication: The authentication options are used for news servers which require a user name and password to access the newsgroups. If your news server does not require a name and password, then you should leave this option alone. Authentication is located under the Configure menu. Acceptable File Masks: Newsbot allows you to specify which types of files will be downloaded. Specifying "*.*" will enable any file to be downloaded, and this is the default. For example, if you only wanted to receive images, then you may wish to remove *.* and add in *.gif and *.jpg. If you only wanted archives, add in *.zip. etc. Dupe Checking: Two different types of dupe checking are supported. They may be used independantly, or you can use both of them at the same time if you wish. By default, the dupe checkers maintain a list of approximately the most recent 2048 messages received. * Subject Dupe Checker: Remembers duplicates by keeping track of the subject of the message. Normally, the Dupe-Subject checker should be used with the "Consider 'From'" setting checked as enabled. Thus, if the same person posts multiple messages with the same subject, the message will be flagged as a dupe. This is useful for preventing download of crossposted messages (i.e. identical messages posted in multiple groups) * Filename Dupe Checker: Remembers duplicates by keeping track of the names of the files that were downloaded. This is very effective at weeding out dupes, but has the side effect of sometimes deleting messages that are not really duplicates. For example, there are a lot of files name "1.JPG" out there! Both of the two above mentioned dupe checkers have some options that control their behaviour: * Reject Duplicates: If checked, then dupe checking will be performed as stated above. If not checked, then no dupe checking will be performed. * Save dupe list: If checked, then dupe information will be saved from session to session. If not checked, then dupe information will only be kept for the current session. * Items to Keep: This is the number of items to "remember" for the dupe checker. A bigger number here will remember more messages (or files), but will also require more memory and/or disk space to hold to dupe checker information. * Consider "From": If enabled, requires the from fields of two messages to be identical for the files to be considered duplicates. A good idea for the dupe subject checker, but probably not advisable for the dupe file checker. * Consider "Lines": If enabled, requires the number of lines of two messages to be within a 10% tolerance for the messages to be considered duplicates. For multi-part files, only the first message is considered. AutoSave: Automatic save is used to automatically save the current state of Newsbot periodically during operation. This is useful since if Newsbot crashes, Newsbot will be able to start back up at the correct position in the newsgroups and with all of your dupe checking and lockout information enabled. There are two types of autosave: * AutoSave Pointers: Saves message pointers. These pointers tell newsbot your current position in the newsgroups, i.e. how many messages you have already seen in each groups. * AutoSave Everything: This saves all state information, including the dupe checkers (assuming the dupe checkers have saving enabled), HTTP grabber, lockout lists, messages pointers, etc. Auto-Encryption: Auto-Encryption is intended to keep files that you download "private". This is primarily in case you are downloading sensitive information that you don't want unauthorized people to be able to access. If Auto-Encryption is enabled, then files will be encrypted with a key that you specify. Only those persons who have this key will be able to retrieve the information in these files. Note #1: Be careful when you pick an encryption key. If you forget what you picked, then there is no way to "find out" what it was. Case is important, so make sure you know what parts (if any) are capitolized. Longer encryption keys do offer better protection. However, my algorithm is by no means perfect, and someone with enough time and computing power could undoubtably crack the code. Note #2: Encrypted files cannot be "read" by another other programs until they are decrpyted in some manner! No other program except Newsbot and it's associated utilities can deal with files encrypted in this manner. There are two ways to retrieve (or "decrypt") encrypted files: * With the built-in jpeg viewer. The built in jpeg viewer will automatically detect encrypted files and prompt you for the decryption key if necessary. * With decrypt.exe. Decrypt.exe (and for that matter, Encrypt.exe) are standalone utilities that you can use to encrypt and/or decrypt a series of files. Once decrypted with decrypt.exe, a file may be read by any other program. To decrypt files, use a command line similar to the following: decrypt key filename.ext Where "key" is the decrpytion key and "filename.ext" is the filename that you want decrypted. You may use wildcards in the filename and decrypt.exe will decryypt all files matching the specification. Decrypt.exe will not "mess up" unencrypted files, nor will it improperly decrypt a file if an improper key is supplied. Decrypt.exe and Encrypt.exe have some additional options. Run the program without any command line parameters to get a list of applicable options. FILES.BBS Generation FILES.BBS files are used by bulletin board systems to catalog files in download directories. If you're the sysop of a bbs, then you may find the automatic FILES.BBS generation useful. Otherwise, it probably won't be of much interest to you. Newsbot can create a variety of different FILES.BBS styles; You may select whichever one works best with your bbs. If none of them do, then you can probably find a conversion or import program for your bbs software which will do the trick. The various styles are listed in the listbox. Selecting "none" will disable files.bbs generation. By default, Newsbot will generate a FILES.BBS file in each directory that files are downloaded into. The FILES.BBS file will be "appended", not "overwritten". You may specify an alternate filename if you wish. If you include a drive/directory in the filename, then all groups will be listed in one big file. The "Convert to 8.3" option will put standard DOS 8.3 (filename.ext) filenames in the FILES.BBS rather than the Windows-95 long filenames. For example, "longname.jpg" would be entered as "longna~1.jpg". This may be useful for bbs programs which do not understand long filenames. ------------------------------------------------------------------------------- Statistical Options There are a variety of options listed under the statistics menu item. Most of these simply return information that SBNews has collected while processing newsgroups. * Similar NewsGroups: Newsgroup headers contain an "Xref:" line which lists other newsgroups to which a specific article has been posted. Many times, a poster will "cross-post" an article to multiple groups which share the same interests. The Similar Newsgroups list will display all of the accumulated Xref's for the current area. * HTTP Grabber: The HTTP Grabber automatically keeps a list of any WWW addresses that are found in the text and/or subject lines of downloaded messages. In addition, a HTML file called HTTPGRAB.HTM will be written to the newsbot directory. You may load this file with your WWW browser and look up any references that SBNews found. * Dupe File List: The list that the dupe-checker keeps in memory to catch dupe files. * Dupe Subject List: The list that the dupe-checker keeps in memory to catch duplicate subject lines. * Latency: A measurement of how long it takes your news server to respond to a command message. Times listed are in milliseconds (1 second = 1000 milliseconds). Slower or highly-used servers will have greater latency times, whereas faster servers will have low latency times. If you are using other Internet applications at the same time as NewsBot, then the latency figure may rise. ------------------------------------------------------------------------------- Coord: The Newsbot Coordinator Coord.Exe (only available in 32-bit version) may be used to synchronize the dupe-checking capabilities of multiple news robots. Running multiple Newsbots at the same time may allow you to better utilize some of the slower news servers out there. To do this, you must run COORD.EXE before loading any instances of Newsbot. Some notes about using Coord: * Coord should be considered EXTREMELY BETA. It seems to be working for most of our testers, but there hasn't been time to conduct widespread testing at this time. * Make sure you run it before loading any newsbots. * Coord is used to run multiple newsbots at a time -- if you only want to run one newsbot, then don't bother with it! * Coord has it's own preferences for the dupe checkers -- you might want to be sure to set them to what you want. * Dupe Checking Statistics in Newsbot will be unavailable while running coord (use coord's dupe statistics instead) ------------------------------------------------------------------------------- Unfinished Stuff Although most of the core of Newsbot is finished, there are still quite a few bells and whistles that I'm planning to add. If you have any features that you would like to see that aren't listed below, then please email me. The following are some of the more important things on my list: * Ability to specify search filters (i.e. only retrieve messages with xxx in the subject field) * User specified download paths * Multithreaded operation in 32-bit version ------------------------------------------------------------------------------- Acknowledgements I would like to thank the following people for their help, support, or contributions to SBNews/Newsbot: * The many people who've helped me beta-test! * The Independent JPEG Group * The ISO Jpeg Standards Committee * Brian Kantor & Phil Lapsley (RFC977) * S. Barber (NNTP Extensions document) * The Papa winsock site * The Tucows winsock site * Lars Magne Ingebrigtsen, "Notes on News" ------------------------------------------------------------------------------- Registration SBNews/Newsbot is a shareware program and as such, you are only granted the right to operate it for a limited time to evaluate it's performance. Continued usage requires registration in the amount of $15.00.
