Dear all and dear Diana,
these communities you mention are really the lighthouse projects in Germany. Great places for community living experience and partly permaculture (as in "agriculture") indeed.
There is a relatively new community in Southern Germany, somewhere between Stuttgart, Nürnberg and Munich, called
Schloss Tempelhof. (Unfortunately there is currently no english version available. It's in the process, I think.) And yes, I am living in that place myself, moved here with my family just a couple of weeks back. It started with some 20 people, and now, there are around 80 adults and almost 30 children. Great place, very innovative, really driven to change something - here, in Germany, in Europe, in society and economy. Lot's of seminars around social permaculture, community processes, alternative schools, permaculture, personal development etc.
Next time you're around in Germany Diana, don't hesitate to step by. Would be great to share our experiences with you. We would surely be interested in organising a seminar with you...
Best wishes,
Stefan
