I am an admin in en.wikipedia, he.wikipedia and he.wikisource. I also frequently write in translatewiki.net, en.wikisource, ru.wikipedia, ca.wikipedia and some other projects. I am a member of the Wikimedia Language committee. In 2011-2012 I was a board member of Wikimedia Israel.
I received a B.A. from the Hebrew University of Jerusalem in Hebrew language and Structural Linguistics.
This is my personal account. For living I work in the Wikimedia Foundation's Internationalization team. My official account in that capacity is Aaharoni-WMF.
