I tried to write up a short summary of what was discussed at the meeting and posted it here with the meeting announcement.
In an afterthought: How about making it an ACTION to create a crowdfunding for the Baumhaus weekend?
Another ACTION idea from my work:
Write an Action Protocol for setting up a sustainable bulk buying club (for organic, faritrade and locally produced food) and try it out. I have people In Prenzlauer Berg (through foodsharing) who are interested and DickesBee food-coop who have already researched all the contacts to producers. There is a manual to base the Protocol on, so it should be fairly straight forward.
