Don't take my words offensive OP but the story that you've just told doesn't add up very well. The main fact of it all is that if Mr. Satoshi seemingly "vanished" from the forum with no (apparent) trace so far, I believe that he underwent an extreme amount of work hiding his marks off the Internet.

Why would he simply appear one day in this same forum that he created, claiming that he created a new user and even created a thread to tell his story? Something doesn't add up here. I'm sure that whoever and whenever Mr. Satoshi(s?) is/are he/they are safely enjoying their wealth and will be forever in the books of technical history as the person/people that created the first digital currency.

I'm still open to accept that you are indeed who you claim to be, if not by sending some kind of proofs that only Mr. Satoshi would have to the forum administrator or something like that.
