Personally I loved reading the German magazine "Amiga Magazin" by Markt & Technik and going to the "Messe" in Koln. The community in Germany was always big...
The highlight of several vacations where we drove through Germany (from Norway, via Sweden/Denmark), was picking up Amiga and C64 magazines mostly from Markt & Technik ... They, combined with Das Guru Buch, were probably the main factors to get me to actually care about doing well in my German lessons at school.
(Ok, I just realized I claimed that the highlight of several of my summer holidays was to buy computer magazines - at guess that sounds a bit sad
)
64'er was fantastic. I hope someone will contribute copies of that. (EDIT: I see
http://www.homecomputerworld.de/ has a bunch of articles etc. from 64'er, but unfortunately not full issue scans)
Also, people, don't forget the Amiga Magazine Rack, though in general the pages available is quite spotty it also has a few non-English magazines:
