I have AIM, MSN, Yahoo, and ICQ, so pick one. I don't think we can have a group chat on MSN though.

Just go to AIM.com and sign up for a screen name, it's no biggie. I recommend downloading Trillian (www.ceruleanstudios.com) as it is the best IM client out there.

Then you can join the chat, mang. No big deal.
