Where can I download the latest (or the one that works...as if you were using it on a PC) msn for IMac? I've been searching but there are so many different versions?? 3.0? 8.0? beta version? mercury..??? I saw on yahoo.com that you can download the 3.0 beta version msn for IMac there... will that work? I have heard so many different types of messenger and different types of versions # (plus some bugs peoples have been experiencing). Can someone please help me?
