I am a german mathematician and mostly active on the german Wikipedia since the beginning of 2004. I am a member of the board of Wikimedia Deutschland e. V. I am particulary concerned with methods to improve the quality of Wikipeida. For the last roundabout two years, I intensively worked on Flagged Revisions.
