1, 2, and 4 exist in the staff forum. 3 was permanently deleted at some point (it must have contained Satoshi's real name and address).
Damn I wasn't expecting to see the post of Satoshi himself in the link, I had goosebumps reading through the replies, after all these years Satoshi has been a mystery unsolved. What if he is still amongst us in the forum? What if he is watching us through a guest or probably a secret account? I guess we will never know.
