Downloading codes on Xbox.com

[Birbo]

I recently saw a thread about downloading codes on xbox.com (like the gold lancer for GoW2) to que up on your 360 the next time you start it up. For the life of me, I can't find the info anywhere! What I'm really looking for is the link for the Left 4 Dead demo (which is no longer on the marketplace). Any help would be greatly appreciated.

MS has already fixed this little loophole.

What Syn said. They're still located on the marketplace, but like 999999 points. However, you can still download 'legit' content like gamer pictures and stuff, and it will download when you power up the 360.
