Hey, saw this and figured I'd see if you still needed help with it.
"what happens if we change your name on xbox how do we change it her?
just wondering for future references."
There are 2 ways. Either through the User CP (scroll to the bottom of the page, look at the menu on the left, select 'username request'). Or Enterring a 'request login name change' through the 'Help Desk' on the main forum page.
Take it easy,
