...and you need Tor to connect to IRC? I've connected to IRC with a proxy before, and I didn't use Tor. If a server doesn't allow it just freakin' use a normal proxy or a Java/CGI:IRC client. Geez.
Also, I understand this is an anonymous BBS and the adavntages to being anonymous, but some people take it too far. Just make up a name, join the server, and join the channel. It's not like anyone is going to trace your hostmask back to your exact location (not even sure if that's possible, and if it is it's probably a lot of work to do) and come stalk you. Seriously, what do you have to hide?
