You might consider exploring other posts from theymos during that period, such as this one: https://bitcointalksearch.org/topic/m.417531
Well, thank you for that link and some clarification. The link is about the transfer of Forum domain to another and I don't think my question has been properly answered. I bolded some part of your comment which is the genesis of my initial question. I know it doesn't make any difference but if Satoshi himself appointed thymos as the admin, it could mean that thymos knows Satoshi or vice versa. I don't want to believe someone built a platform and all of a sudden, he left everything under the control of total strangers whom he never knew or met and disappeared. I might sound childish but thymos probably know whereabout of Satoshi, either dead or alive.
It was probably not all of a sudden. And as far as I know, theymos was not the only admin on the forum. You will notice that he is one of the oldest members and joined the forum only a few months after the forum was created. So it makes sense that Satoshi chose members who were active members of the community at the time and showed an interest in technology in the earliest days of Bitcoin. This does not necessarily mean that they knew each other or ever met in real life.
