Question About Name Change or Creating A New Account

I was wondering if there is a way you can change my name on here? Or is it ok for me to start a new account and abandon this one I am currently using. I don't go by this name on any other forums, or game sites, and I do post my videos I do on Youtube on my blog, and so on, and I am trying to be more active around here. So if I could get a name change, that would be cool, if not is it ok for me to create a new account?

Thanks
