Something to think about...With some kind of collapse coming, communities will need barter exchange coordinators; someone who keeps track of who has what so that people in need can find people who have product. Will that person be you? Time to build back better barter networks. Some barter profit potential here also.
I'm not talking about building a commune. These would be people throughout the larger community WILLING to participate & offer barter. Skeptics or those who require convincing would be immediately discounted. A barter economy will not succeed unless people can find what they need.
