If any of you still have to do the vidmaster challenge I will sign on at around 6 - 6:30 est and be on until 10 est. Send a friend request to my gt - Curse You - to do the vidmaster challenge!
You probably should of made this in the Halo3 Matches section it would of got more attention for those wanting this achievement. I would ask a Mod to move it (just my opinion though)
