Ok, two things. One is if you play call of duty world at war what is your screen name? Second on the campaign mode I just drove around in the tanks and stuff but it says re group and I've driven everywhere and can't find the rest of my team. Can anyone please help me? Thanks! :D :D

(Haven't played Call of Duty, but been told I'd probably like it since I liked Medal of Honor.)
