Sue mentioned that the guys at Wine Berserkers use Ajax Chat and she got logged on immediately. It looks like it uses PHP and HTML so needs some sort of installation work. Probably not a lot, but I have not registered with them to see what comes back.
http://www.ajaxchat.org/It looks like the software has not been updated since 2006. Not sure if that is a good or a bad thing. But it is free.
One interesting comment...
Chat TerminologiesMoof = becoming disconnected from the Internet and/or the chat for no apparent reason. If you have call waiting enabled on your telephone line, you'll moof alot!
So is anyone moofing a lot while chatting?
