So when it comes to anything i use my REAL username "RAS902"

I made this account with "Wam11" waayyy back when i played Starcraft and Brood Wars.

But since then ive used RAS902 for everything. including my xbox360 gamertag, i would really like to make it my username on here, gamespot, as it is one of the few things i find important enough to spend my time on.

Is there anyway to change my username to RAS902? I am pretty sure no1 is using it and it would make my day just so amazing
