- W H A T I S LearnCHEM?
-
- LearnCHEM 2.0 is a learning aid designed for kids and students at
- elementary and high schools and undergraduates of the subjects which are
- more or less related to chemistry - i. e. medicine, chemistry,
- and physics. This program should help them learn chemistry more easily.
-
- LearnCHEM consists of two parts:
- 1. the PERIODIC TABLE of elements displayed in four different colors with
- brief descriptions. You can "walk" the table using the cursor movement keys.
- 2. FORMULAE OF ORGANIC SUBSTANCES - THIS IS SOMETHING COMPLETELY NEW,
- SOMETHING THAT HASN'T BEEN HERE BEFORE. Nowhere else can you find
- this option. From the list you can choose whichever organic substance
- you like and which is present in the database. The program allows for
- displaying the structural formulae of all the common organic substances -
- alkanes, alkenes, alkines, alcohols, carboxylic acids, alkaloids, aldehydes,
- steroids etc.
-
-
- LearnCHEM is SHAREWARE. You may copy the unregistered version, use it, give
- it to your friends, upload it to a BBS on condition you distribute the whole
- and unmodified original package.
-
- LearnCHEM is inexpensive shareware. If you like it and continue to use it
- after a trial period of 30 days, you should (actually, you have to) pay
- a small registration fee. As you can see, you can test this program freely
- before buying it. If you do not want to register, you have to quit using it
- and delete it.
- When should you register? Now!
- To get to know the advantages of being a registered user, please read the
- lines below.
-
-
- IN WHAT WAY WILL THE REGISTRATION BE OF ADVANTAGE TO YOU?
-
- If you register and pay a small fee, you will receive the registered version
- - with the full database of the structural formulae of organic substances,
- - which does not force you to wait 10 seconds and read the notice about the
- registration after running the program,
- - and you will be given two more upgrades (You will be informed by mail and
- asked to send the old registered version diskette) for free.
-
- Remember, by registering you contribute to making the program better
- and better.
- Besides, if I encounter a great number of registered users from certain
- countries, I can promise them I will make their mother-tongue language versions
- and send them for free. Please let me know if you like this idea.

- NOW FOR THE REGISTRATION FEES
-
- First, how can you pay the registration fee? You can either send cash or pay by
- International Money Order, US Postal Money Order or travellers cheques.
- Please do not send any other cheques (it involves high costs to me and,
- in fact, to you too because the banks charge enormous fees).
-
- Please probably pay by cheque (you should avoid sending coins which may draw
- the unwanted attention of some people during the delivery).
-
- It is impossible to pay by COD (cash on delivery) or by credit card.
- 1. If you pay cash, please put it in an envelope and make sure no one can see
- what is inside. Please send it by "registered mail" or "recorded
- delivery". If you pay cash, every convertible currency mentioned in the
- REGISTRA.FRM will be accepted.
- 2. If you pay by IMO, US Postal Money Order or travel cheques, put them into
- the envelope. Please add US $3 to cover exchange expenses. These cheques
- and money orders have to be payable only in US $, British pounds or
- German DM.
