Ok, I switched to mac not long ago and was just a little annoyed with the lack of support for YIM, then yahoo released their beta so I was cotent. Microsoft, however, has not released a Mac version of Live Messenger, and I doubt they will do so in light of Jobs's slurs on Vista during his keynote (which were completely justified). Anyway, I was looking through stuff on the web, and an article popped up about aMSN on mac, with video chat and nudges and stuff. So I popped over and checked it out, downloaded it and lo and behold, a messenger better than what microsoft could pump out... considering that these people aren't payed to make this software. Linux users probably already know about it seeing as it is THE best MSN messenger for Linux. I had used it for my distro of Linux before, but had no idea it was out for OS X, let alone in UniBin format. I don't know if forum people can put this on the front page, but I'd think it should go there simply because alot of new mac users don't know about this and it is one of the most helpful tools for someone migrating from MSN on the PC to MSN on the Mac.
