Is it the bitcoin foundation?
No. The Bitcoin Foundation has nothing to do with the forum.
Both bitcoin.org and bitcointalk.org are owned by me and theymos, though I'm more active on the bitcoin.org project, and theymos is more active here.
Satoshi and Sirius used to be involved, but they're not active anymore.
Since you and theymos own bitcointalk.org, why is it that your account only ranks as a Jr member instead of an administrator for example?
Or is it due to the fact that you only focus on bitcoin.org as you are more active there as you said?
I'm not very active here, and theymos and other staff are running this forum very well, so I prefer to put my efforts into bitcoin.org.
Being a Jr member isn't so bad. It comes with some advantages, such as not having to deal with people messaging me about forum issues like I would if I were an administrator.
