The new article feature has been disabled for the german language wikipedia "for performance reasons". That was really a bad idea - the admins need that feature to look for nonsens articles and so on. In the effect, now the "recent changes" must be used a lot more, which IMHO will increase the server traffic more than the "new article" page did. So please re-enable the new article feature again.
By the way, it would be nice to announce such measures.
