“If you need help, you can contact one of our German speaking editors or ask on the Users Mailing List. ” (link)
Well, not any more, the mailing lists are dead of course.
By the way, the link for German speaking editors refers to a wiki page that may be quite out of date, and is duplicated by the languages in the user profiles. Shouldn’t it link to the latter instead (if it is possible to get a list based on the user profiles)?
