I read Satoshi Nakamoto was a member of this forum. How true it is, if it is then his member account is still active, I guess.
The account is already known and his posts has a lot of merits.
He left Bitcoin and this forum years ago and I don't think he will be coming back.
He's account is still there, that is the only ideas and knowledge he left. That is just like James Halliday's gallery in Ready Player One that you can visit and read all over again.
