GT: BigstickToucan
My old Bungie.net account was created February 6, 2008. Unfortunately, I had signed up using my brother's email account (we then shared an Xbox Live account which was linked to my old Bungie.net account), and he changed the password, meaning I couldn't log in. Thus is why I have this account.
Go to Walmart and buy a new Xbox, and after Halo 2 goes offline, take your Xbox back.
