I have a 360 but only recently pulled the trigger for Xbox Live Gold and am waiting for it to ship.
Had a question about my gamer profile though..is there a way to transfer my offline gamer profile that I've had to the new profile that I will have when I get XBOX Live? I don't want to lose all the achievements and whatnot that I've spent time getting. Also, I made a profile on the Xbox site if that makes any difference with the process. Any advice would be appreciated!
