OPs community sounds VERY different to ours but these are my answers to the questions posted above...
Do the members go out to work outside the community? Yes, in all sorts of jobs. Some work from home - we have a welder, a mechanic, a silversmith, and a potter all with workshops here.
Are they allowed to sustain friendships with non members. Hell yeah. We have a constant stream of peoples' friends trooping through - I think we meet way more diverse people here then we did living in a house in a town. We also have regular visitor weekends as well when anyone interested can come and visit and see what we are all about.
Are the children home educated? Some are. Mine used to be but aren't now.
Do you get enough privacy? I have my own front door to my own living space. We do have a shared kitchen, bathrooms, and living room that we can use if we want to though.
Do you take all your meals together? Nope. We do have an fortnightly communal evening meal rota but it is voluntary and it only runs on weekdays. The rest of the time we fend for ourselves 
as we do on the nights when a crap cook is on the rota
What values do you all have in common to determine the nature of the community? Commitment to co-operative living (it wouldn't work otherwise!), and to lowering our environmental impact. Its also a vegetarian kitchen and all shared meals are veggie but we can eat what we like otherwise.
There are as many set-ups as there are communities though. They vary massively in every respect - we had a visitor last week who told me she had been to one place where every member had to spend one night a year sharing a bed with every other member in turn 
and the reaction of everyone round our table was 
followed by Fuck That.
