Name Change Question

When I joined this community I used a Gamertag (stupid me) as my username. I now am looking into buying a license now, but don't want this silly name as my Forum Username anymore. Is there anyway an Admin can change my username for me before I buy a license? Thanks :)

Also, the only reason I don't just make a new account is because of my email. I'd rather keep my 4 year old email that I will always have access to.
