free basic services + small charge for added "freemium" service
This service connects people who are interested in creating some kind of intentional community (e.g., cohousing, commune, shared housing). It's like a mashup of a dating site and roommate finder. Profiles anonymous. Provides info on grants available for individuals who seek to set up a community house for some kind of social service type housing, so you don't have to be a non-profit.
