Errr. I have a problem

I don't like this username, you notice the "_"? I hate it, I'd like to change my username but I can't cause it says my email has already been taken, (by this username, obviously) and I don't feel like creationg a brand new email acount just for the purpose of having a new nickname, is there any other way?

All help is apreciated.

Ok forget about it, It's all ok now
