Achim Raschka is zoologist and author in the German Teknopedia since 2003. He was a founding member and former board member of the german chapter of Wikimedia (have a look at Wikimedia Deutschland) and together with others is organizing several project like the german writing contest, a contest on writing miniatures, the Teknopedia:Festivalsommer (a project on concert photography) or the local community place Lokal K in Cologne.
I am admin in the German Teknopedia but the main focus of my work is on articles, mainly on zoology topics (in the moment mainly mammals, especially squirrels) but also on arts, games and others. For more details please have a look at Achim Raschka in the german Teknopedia.
