While I was in Tucson, Arizona I stayed at a cohousing community, asked questions, and observed how it all worked. I was invited to listen in on their community meeting, which included budget talks. I made a Mindmap of relevant thoughts and many things I had observed relevant to creating and maintaining a cohousing community. legolastn asked that I post it on LiveJournal. If anyone wants the actual mindmap data file I can look into exporting that as well.
Edit: Eh... the program didn't generate or attach the image correctly. Will try again when I get home this evening.
