I signed up last week. Now I want to change my username/screen name. I couldn't find any way to do it through the "My Account" link. So, I logged out and tried to create a new account. But, I was denied because my e-mail address was already associated with an account. So, I thought that I would delete my old account then create a new one. However, I could not find any way to delete an account, either.

So, am I stuck with the username that I created when I initially signed up?
