Hi sorry to ask but is there any way you can help. My son has only had his xbox for a month and is really enjoying it. He did however change his gamer tag by himself (I believe he gets one free) and has spelt it incorrectly. He put in musturd700 instead of mustard700. I believe it takes 800G to change it again (which he doesn't have). Would it be possible to correct the spelling mistake or is he just stuck with it.
