I'm sure someone here probably knows how to setup an IRC chat for NEWGN'R, it's old as the fucking hills
Sure, I've done it. #newgnr at Undernet.
For people unaccustomed to IRC:
1) Download and install an IRC client (e.g. mIRC from http://www.mirc.com/get.html
2) Log onto an UnderNet server
3) When you're asked to enter a channel just name type newgnr
