I bought Trillian Pro recently, and I was able to solve a little quirk on IRC (auto-join and stuff) with some help yesterday. Now the change is complete for me. I can connect with multiple IM protocols (AIM, Yahoo!, MSN Messenger, ICQ, and IRC chat rooms), and I can organise my contacts the way I want to. The Pro version offers something called Meta-Contacts, which allows you to take one person’s multiple accounts on the different protocols, and place them in one contact entry on your contect list. Everything can be organised into sub-groups, making things easier to find.

How could I ever go back to MSN after this?
