If Craig Wright is the real Satoshi, and wants to prove it, ALL he has to do is sign one new message with an address known to belong to Satoshi and post it on here.

Junior members do this routinely in the lending area to prove they own an address but the creator of Bitcoin can't figure out how? Give me a break.

He's either not Satoshi or wants everyone, except Gavin apparently, to think he's not Satoshi.
