irc.quakenet.org #NexusLAN
During the post NexusLAN 11 discussion we wanted to make communication a little more fluid, so we created an IRC channel. You are encouraged to join the IRC channel during the event, but feel free to hang out before and after as well. Doesn't have to be LAN oriented.
irc.Quakenet.org in general has some pretty good gaming channels.
