I've tried to set up 2 intentional communities since my hubby up and lost his mind, the farm and his life. It really comes down to people selection, and screening. IF I ever tried for that "third time is the charm" community, I would have a 3-month trial period. And very clear rules. Free-loaders and slobs are difficult enough when they are family...but bringing another into your personal space just to get taken advantage of is disheartening. Frustrating. Time consuming. Irritating. And getting rid of them can be difficult without CLEAR written agreements.
Sound like an old bat, don't I?
Just the voice of experience. I've cooked and done dishes for 4 adults, bought the food, done the chores, paid the bills, maintained the home and gardens only to have been overlooked when paychecks came or days off allowed a bit of labor. And I'm not talking building raised beds or a barn, but simple stuff like sweeping a floor, or taking out recycling. Make sure you have found people with PURE intentions. People that are crazy in a good way, like me!
That said, I would actually like to find a nice community, and join in. I'm in college full time (on-line) but great with kids and critters...and can weed and water like a pro. Years of experience and knowledge to share...which keeps me coming back to threads like this. I have hope in humanity's overall good intentions.
