Everyone, challenge lobbies are not real and won't be for a little. When they are, you will hear about it (trust me). For now, all of you guys asking for YouTube subscribers are fake and it IS against the new updated rules for TU7 (not trying to act like a moderator, but just informing). Take a look at it before you post: Forums/t=3406236/mw2-modding-sect...rules.html

Sorry if I am doing something wrong, I was just trying to help the community get a better understanding.
