Yup, there's dear old Elizabeth (alias "Cammie"), and like I said on
link, I'm secretly Tina Fey.
Belief or disbelief rests with you, but I am who I am.
In all seriousness, though, I doubt it. Even if there were, they'd be unlikely to reveal themselves... But like I said, I doubt it. First of all, they have very busy lives, and second of all there are sometimes legal things in their contracts about viewing and/or participating in unofficial fansites, fan fiction, etc. So yeah, just my two cents.
