is there away other then just leaving it blank?

As far as I know right now, you can't delete your account. You just abandon it if you don't want to use it anymore. :x
Not entirely sure though. I think it MAY be possible (but not a preferred choice, I think), but you'll have to wait for an AA to confirm/deny that. =)

There is no way to delete an account. If you don't want to use it anymore you can just leave it to rot.

Nope! Cant do, wont do, negative, ect ect.

Though one would ask why you want to delete your account in the first place.
