I just stumbled across this trying to find a local barter group.

This is an introduction, overview and directory of links to a wide variety of ideas and projects that help create stronger, healthier community. We start by looking at a number of alternative and experimental forms of community, including ecovillages, cohousing, intentional community, cooperatives, related topics and links. We then look at a variety of creative ways that you can find or create stronger community where you live today (without moving or joining an alternative community). We include resources on how to go about this, and the interpersonal issues and group process that can be involved. We also look at the "Healthy Community" approach, and how it can lead to a better lifestyle and a more sustainable world. This page includes definitions & examples; related events; organizations; publications; listings; links; how to find or create a community, more.
