The same Oop as on English Wikipedia (en:User:Oop since 2004) and some others. Also, an admin on Estonian Wikipedia (et:Kasutaja:Oop since 2005). In 2011-14 I was a member of the board of Estonian Wikimedia chapter, Wikimedia Eesti. Since February 2014, I'm no more a member of WMEE and I have almost retired from Wikipedia, too. I'm still acting as a wikievangelist, writing in media and working on establishing Freedom of Panorama in Estonia.
Amongst other things, I am or have been a translator, writer, journalist, editor, copy editor, and PR specialist. I have studied philosophy, philology, and assyriology.
