Not sure if there has been a thread on this or not. Anyways my girlfriend is introduced me to this program and can be used to IM in game when in fullscreen mode. There's a ton of supported game; eq, wow, eq2, and etc just to name a few. Link is down below if anyone desides to use it

I've had it for a while but all of my friends use MSN only... I played CS/q3 religiously and i went to lan parties a lot. Now i alternate between EQ, CS and BF2.

Is there a plugin for Trillian for this by chance?

Not sure why there would be? It looks like just another IM program to me (and too many junk features added on for my taste :P).

Hehe that's all AIM ICQ and MSN are to me.

Yep, that's why I use Trillian!
