So I keep getting more and more of these invites, and less and less people to give them to. Email me if you want one! Want to know more about Windows Live Messenger? Check out the WLM site.
I personally think v8 is a good step forwards from v7.5 - which is the current publicly available verison of MSN Messenger. I do believe however that it is a bit cluttered with ads. This being said, there is a patch that will work that removes ads. It's available locally or from the original site.
