DGS-ALSMOD - RBBS Lines Modified for Alias Support
DGS-ALSNM  -  New Lines used to Provide Mail Notification w/Aliases
DGS-MNMOD  - RBBS Lines Modified to Support Mail Notification w/Aliases

  This Mod adds the ability to Support Aliases to RBBS-PC 17.1A
  Aliases Are turned on/off by having/not having a file with the
     extension, A.Def, using the Message Files Name as in ADULTA.DEF
     for the Adult Conference/SubBoard. It is located on the Same
     Drive/Path as the conferences Users File.

  There are 3 modules added to the code.
  DGSALIAS is used to Get or Create a Users Alias.
  GOODALS  is used to make sure that the users requested Alias
           does not exist and is not another users Real Name.
         * Also Ensures 'SYSOP' and Sysops Name are not Attempted. *
  ALIASCHK is used to support the RBBS Mail Notification feature.

  Further Notes - The Alias Mod looks for an appropriate DEF file for
          the conference or subboard.  If found it looks for the users
          record and associated alias.  If found it returns and sets up
          the users name to be the alias. It will treat mail to original
          name or alias as belonging to the user.
             If an Alias is NOT found in the Alias file the user is
          prompted as to whether they want to use one.  If no the alias
          is set to their real name.  If the user answers yes, they will
          be prompted for the alias to use.

  Alias Limits - Max 31 Character Length, may NOT be Blank, can NOT be
                 'SYSOP', or the Sysop's Name.  Duplicate Aliases are
                 checked and stopped.  No real user name shown in the
                 Alias file can be used as another persons alias.  This
                 prevents someone Entering mail as someone else or being
                 able to read another users personal mail.
  Conference Mail Scan is Supported,
     The Real User Name, at Logon will be notified if anyone has left
         mail to either their real name or their Alias.
