hexchat, icechat, webchat, if I remember correctly there was some irc client that had "kiwi" in the name too? haven't used irc in a while, sorry.
as for the ts server it's down, I have no personal intention of renewing it because everyone's generally too inactive for us to need our own server (myself included), and I'm happy to use BC's when I come online during the holidays. if rC still want their own server for whatever reason I'd set it back up again but they'd have to wait until next sunday at the earliest because I have exams pretty much every single day next week and can't really spare the time.
