We have had an IRC chat for around 44 megaseconds now. If you want to come, here's the relevant info:

Server: irc.drx.pl
Channel: #protos

If you download [url=http://www.mirc.com/]mIRC[/url], it's as easy as typing /server irc.drx.pl -j #protos

Or, what should work on all clients: /server irc.drx.pl, then /join #protos
