No. There was also Sirius which helped Satoshi immensely with the Bitcoin project in 2009. My knowledge on the history is limited because I was new at the time, but I believe they both trusted theymos to take care of it in 2010. Sirius gave control of the domains to Cobra. theymos and Cyrus run the forum now. That link appears to be a bit behind the times as BadBear isn't an administrator anymore, he doesn't appear to be even a moderator. He last posted in late 2016 and his account was last active on here in spring 2017.

Satoshi left the project over 7 years ago and there's no point in identifying him anymore. Sirius, who was responsible for porting the code to Linux and getting a lot of early interest (even more than Satoshi) eventually decided to leave the project in the hands of those who were interested in taking it further. The forum grew a lot from 2010 to 2013 and even though the signal to noise ratio hasn't always been the best, theymos and Cyrus have done a great job given the limitations of the software. theymos also runs the subreddit which has grown quite well over the years.
