I don't know whether I should post this here but I can't think where else. I want to change my gametag NAME from what it is (stupid) to something new! But I can't find anything out about that. If it...
If you are wanting to change your GT, then you need to pay 800 msp to do so. You can change it under the "My Account" section on the dashboard.
Nope, its just my avatar name I want to change.
