Tired of running AOL Instant Messenger, Yahoo Instant Messenger, MSN Messenger, ICQ, and IRC to keep in touch with all your friends? Well, look no further because Trillian Pro 1.0 was just released. It combines the 5 different services into one program and adds many features not found in other IM clients. The Pro version costs $25.00 (or a search of Google for "trillian pro download") or you can get their "lite" version (0.74) for free on their site. Either way you'll wind up with a great Windows messaging client.
Many, many more details on www.trillian.cc (I actually feel that I'm not doing it justice in this post- go check it out).
