I usually contribute to the German language Wikipedia (see my user page there), but occasionally I work here (I apologise that my English is not the best). On English wikipedia, I mostly work for "interwikification" purposes. I rarely try to write long texts (articles) here, because I'm not sure whether it wouldn't cause more work for someone else rewriting them than it would take me to contribute in the first place. Also, I have more than enough to do on de:WP. There, I'm very active as author and for years also as admin, having started more than 7,500 articles (including ca. 30 featured and good ones), mainly on topics to do with archaeology (ancient art, mostly depending ceramics), history (at the last times moytly history of classical scholarship) or sports (for a long time biathlon, skeleton, luge, other winter sports and soccer, but now Beach handball). My German edit count stands at more than 241,000, on Commons more than 703,000. I'm Admin on Commons since 2007. From November 2018 until May 2020 I was bylaw at the board of Wikimedia Deutschland.
