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 an admin and author, having started more than 5,600 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 (biathlon, skeleton, luge, other winter sports and soccer). My German edit count stands at more than 160,000. I'm Admin at de:WP and Commons.
A fact from Marcus Cyron appeared on Wikipedia's Main Page in the Did you know? column on 15 December 2007, and was viewed approximately 5,505 times (disclaimer)(check views). The text of the entry was as follows: "Did you know
...that Aline was an ordinary woman who lived in 1st century AD Egypt, and whose name and portrait were preserved in her grave?"
