Many of my friends don't even know anything about the mail and instant messaging acronyms http://www.jabber.org/user/userguide/#acronyms. AFAIK, LOL, BBS, B/C and of course RTFM  >:(

What I'm searching for is a real tiny application (that I can send via email) which allows others to search for acronyms.

Let's say... they start the application and they see a search field. After they've entered let's say LOL, a list appears and an explaination follows what LOL (or whatever) means.

Interesting would be the possibility to add new acronyms without editing the source code.
