Dude, the reason I say AIM is pretty bad is because it's so unstable. It's BSOD my machine 4 times since I installed it, that's pretty unnacceptable considering I've ran MSN messenger for the last few months without a single hitch and ICQ for the last few days with no problems either.
I wouldn't hate AIM so much if it just crashed alone but it takes IE and my mail client with it.
Please if it's at all possible get a different chat program. ICQ will allow you to speak to a great many people in the HLP community as well as speed things up with the model building.
