Language for Help Requests

Hi all,
I just want to take on the last few requests here, which were all written in german – obviously because it can clearly be seen that the maintainer (=me) speaks and writes german ?? .
Anyways, I strongly recommend to write in english (if possible), as this is an international support site.
Not everybody looking for help here, can understand german, and, of course, Q/A here should also be helpful for those.
