If Trillian’s driving you nuts and GAIM doesn’t do enough (or are tired of messing with upgrading GTK), give IM2 Messenger a try.

I just installed is and, I must say, it’s a tad faster and does quite a bit more than GAIM. I’m not sure if it’ll stay around because, well, I use GAIM because it doesn’t do a lot. I don’t video conference, fileshare, mess with skins or any of that stuff. If I did, though, IM2 would be my client of choice.
