I said

I'll bet US$1000 that this is Will_Newsome.

I think it's time to close out this somewhat underspecified offer of a bet. So far, AspiringKnitter and Eliezer expressed interest but only if a method of resolving the bet could be determined, Alicorn offered to play a role in resolving the bet in return for a share of the winnings, and dlthomas offered up $15.

I will leave the possibility of joining the bet open for another 24 hours, starting from the moment this comment is posted. I won't look at the site during that time. Then I'll return, see who (if anyone) still wants a piece of the action, and will also attempt to resolve any remaining conflicts about who gets to participate and on what terms. You are allowed to say "I want to join the bet, but this is conditional upon resolving such-and-such issue of procedure, arbitration, etc." Those details can be sorted out later. This is just the last chance to shortlist yourself as a potential bettor.

I'll be back in 24 hours.
