Super Freaky.
I’ve also been using Fire at work since I started working at a Mac place. I liked Fire.
I also use Trillian on Windows and have for quite a while.
Years ago I tried Adium, but hadn’t tried the new version.
Now that I’m going all Mac-crazy, I downloaded the new Adium and it rocks. I heart Adium. You can even change the Dock icon to something funny.
Just like J.P.
