I don't have Gaim on this comp though. I have it on my laptop which runs on Ubuntu (and Windows XP, but mostly use Ubuntu on it). This comp runs on Windows XP. There are Instant Message apps like Miranda or what's-its-name-again, which I had on this comp a long time ago...I removed them, 'cause I never used them. I do have msn though :)
No, I don't use Xfire, don't play games that much. Usually during christmas holidays and summer vacation.
