Features:
aMSN is "free open source MSN Messenger clone" that has Microsoft Messenger Mac beat hands down, if webcam support was not a good enough reason for you to make the move, then consider that Tabbed chat windows, multiple account signin, file transfer, archives, tabbed messaging, status, Display pictures and Custom emoticons are just some of the features you'll find. If you're after something a little more than what's on offer then check out their Plugins section where you will find little gems like BugBuddy (auto reply), DualDisplayPictures, Emotes, Say It, SpellCheck and so much more, you can also customize the look with skins. Another great thing about aMSN is that you don't need to sign up for yet another account, you simply login with your existing Microsoft Passport.
