Hey guys, I've been using this, and been happy with it. Works much better than Aim, plus it can use ICQ, Yahoo, MSN, etc. Click Here
thats what i use. i like being able to see away messages without having to resort to clicking thru a few options, nice just to hold the mouse over their name and be able to see it.
I don't even have a MSN, ICQ, or Yahoo! name so I stick with DeadAIM. I've used Trillian before and I didn't like it.
