Was among the founders here, moderator from mid-2014 to late-2015 and mid-2016 - present. I also operate the dimension10.admin account for admin-only (non-moderational) duties.
I'm currently writing a math/physics content base called "The Winding Number" (thewindingnumber.blogspot.com) -- check it out!
In the past, I had tried to start a wiki on mathematics and physics. It never really took off (it has exactly 4 users, none are active any longer). If you think you can promote it better, and steer it to the right path, feel free to write me an email at email@example.com, asking for admin rights there.
