Being a member of the forum for the time past. I tried to ascertain the history of the forum as i doubt the administration of the forum. How come the creator is not active and did not stay long yet his absence did not imply on the forum.
Because you're yet to know that his mission is already accomplished which is to see that Bitcoin stays and remain in serving for every of it's purpose why he had created it, what the people want is bitcoin and not Satoshi, if you create as many cars and release them to the people, must you always be around them all before people can buy and use them?.
The question is, could he be that he delegated authority and assigned duties to some people before his departure?
Yes, at least I know of two admin to this forum, Theymos and Cyrus
Satoshi is the creator and founder to this forum and Bitcoin.
