Sorry, you posted this message forever ago and I just noticed now. I think the only way to change your screen name here is to have us delete your account and start a new one. But then you'll lose all your post counts and other history, so that's no good.
That's hilarious that you wanted to be called The Fly... in my league most of us have aliases for the GMs of our teams. My team's GM: The Fly. Seriously! Good to find a fellow fan here.
