Ok so I've been chatting a lot with some PBN people lately on IRC. It's extremely simple to use. And best of all it doesn't require a screen name. It's similar to the chat we used on Otter's site.
Method #1 for joining:
Go to
http://roachware.net/chat
Make a username
Once it connects, click the "Channels" tab, then choose kusachat
Method #2 (most will prefer this once they get used to it):
Download a chat client of your choice. (Silverex is a good choice for Windows)
Server name: roachware.net
Channel: kusachat
I'd like to see this work out, it can really be useful since many don't have AIM. Any questions, post them up here.
