Hello and welcome!
I'm more to PPC than 68k for a change, but plan to get at least Minimig too! To answer your question - I suppose it comes from US but the members are throughout the world. Actually the former owner was from US, I suppose the current one too. But that's fairly international site. If you praise 68k, that's the best Amiga place you could join.
I also started learning German last October (I had been learning in secondary school but that was long ago). And my tutor told me new a joke that I enjoy as my immigration is already scheduled. Here it goes:
Kaum gestohlen - schon in Polen
:-)
Maybe I shoudln't write this but I really think it's funny.
Cheers!
