I hear a lot of people complaining about low ranks joining their games and ruining them, I am one of the complainers, i have a suggestion which might help. If you had another box in Personal menu where players can put players they like to play with in that list so if they ever wanted to start a game they can click next to their names and send them PMs with password. Lets call it a buddy list. I think that might make it easier for high ranks who want to start games, and not have somebody with a vendeta to join their games. I hope this will help.
