Trillian is the name of the best IM client that I’ve come across so far. It allows you to seamlessly integrate with Yahoo Messenger, MSN Messenger, AOL, ICQ, and IRC services all from within one client interface–and it does so very well.
I’ve been using it for the past few days after I was turned onto it from a friend. I strongly recommend it to all Windows users out there who need to have simultaneous access to more than one IM service.
Here’s the link to the official site:
