L33TSig IRC
From L33TSig Wiki
L33TSig has an IRC channel!
You can either join by going to the main site and then clicking the IRC link in the sidebar (as long as you're logged in), or you can use a client such as X-Chat, mIRC or IRSSI.
If you use your own client, connect to irc.l33tsig.net, channel #L33Tsig. The port is 6667 for normal connections, or 6697 for SSL. Don't be alarmed if the name of the server or network you connect to doesn't say "L33TSig" in it ;-)
