Well, here's how we ran it. Everyone had their jobs (Miner, engineer, interior designer, hunter, farmer), and there were no possessions. There was just a big inventory room that we stored EVERYTHING in. If you needed anything for your job, you just took what you needed. No more, no less. This worked out EXTREMELY well actually, because people were working toward the betterment of their community, not just themselves, so everyone helped everyone. The one exception to this rule was the one downfall: While no one owned the diamonds the miners found, we did have one rule about them, you could only use them if everyone in the server agreed with the cause. This was a great rule until a buddy of mine joined the server and before we remembered to mention the rule (it was never really an issue before, so it slipped our minds) he used our only 3 diamonds remaining to make a pick axe for himself. He was never much of a team player anyway. It was kind of a bummer, but it was a slight error in an otherwise extremely successful system. It was a great experiment for me as an anarchist to see unfold. I was very happy with the results.
