Yes, this means that you can log in to the chat room, and, should anyone be there, talk. Now, I don't give my site URL to anybody I know has a virus code, but I still think that your screenname should be a random user name, not your real name, and you should never give out personal information-
I am not responsible for anyone who is blackmailed, murdered, attempted to be murdered, stolen from, hacked into, maimed or other wise injured by the chat room/inhabitants of the chat room... so...
WHO WANTS TO CHAT???
