It's pretty simple. A ton of us have the 48 free Hours of Xbox Live! Gold cards which come with almost all 360 games. They are useless to those of us, who are already Gold subscribers. So the premise is simple. If you want to share your 48 Hours Free Code with another member who doesn't have Gold, post here and let them know you've got a spare code,so you can enjoy the 48 free Hours of Xbox Live! Gold. This will cut down on the million individual code request threads.
