Are you already registered to have the site track your GS? I notice your GT card is not being generated. If you weren't previously added, you're out of luck as the whole xbox.com feed is screwed up and we can't add anyone else.
Hey, any reason I shouldn't be on the HALO 4 leaderboard? I've marked the achievements I got and that should put up to 6th/7th? Even if it is for 2 hours, I would love to see my name on there before everyone gets the game!
