I'll be more than happy to fess up to all my MPD's because I haven't used any of them here on this board.
RollFaster (used on bicycling forums)
Reverend Howell N. Shreack (used on religion parody role-playing forums)
Admiral Worthington Scrimshaw Esquire (used on adventure role-playing forums)
Jubilation T Cornpone (used on hillbilly role-playing forums)
Konrad Klutz (used only once on the Jesus Cafe forum, and I got banned on the spot just for a silly joke)
Krissypoo (used only once on Talk City and it instantly brought scads of pedophiles out of the woodwork)
So there you have it, folks, if you see any of them here you'll know it's me.
