The past half year I was squatting with like-minded friends which turned into a sort of intentional house. There were about 8 to 10 of us there at a time. We shared everything, it was intentionally freegan (all food dived or racked). We all practice mostly subtle forms of anarchy, and would team together for certain regional protest actions. As each of our houses never lasted more than 6-7 weeks each, we never got gardens going but with a more stable place we would have loved a garden. We all taught each other our skills of squatting and together we were strong in all aspects.
I started a house project with another group, which was based around more structured written intentions but that one took ages to get going and by the time we had secured a space I had left to go traveling. The houses I lived in for a while wasn't exactly an 'intentional community' per say since it wasn't heaps structured but I think it functioned in relatively the same way. I absolutely loved it!!! Would love to do something similar in the future, possibly in a more stable way (eg. getting an agreement with the owner) and having intentions with everybody on basically the same page. Slightly larger scale would be rad too. All of this took place in the suburbs of Melbourne, Australia which I enjoyed, can't beat the resources of a city (dumpsters, empty houses, building supply stores).
