Well, we can give it a try! I was thinking for some reason there was some additional numbers or something you needed to find the right server connection, but I can't find them on my current program (Snak, which is the Mac version of mIRC). I'll give you the server name and room (channel), see what happens. If you can't get in or if we're not in the same place, let me know on here and I'll go see if I can look up the other numbers.

Server: irc.squidge.org
Channel: #tinman

ETA: Looked up the Port number: 6669
(just in case that helps!)
