I've just set up MSN to work through Jabber, in iChat 4. It's not perfect (smileys not all the same, file transfers a bit dodgy/filesize limited), but it's a lot slicker generally than MSN for Mac. I was wondering how to block MSN people in iChat? When I right-click on their name, "Block Buddy" is greyed out. With AIM/.Mac buddys this isn't a problem. Can anyone help?
