Do you know about Time Banks?

A good friend of mine just told me about time banks. As someone who started both a babysitting co-op and a food co-op back in the '70's at my (now ex) husband's grad school...I love this idea.

Have you had any experience with them?

Here's how they are described at www.timebanks.org:

Time Banks Weave Community One Hour at a Time

For every hour you spend doing something for someone in your community, you earn one Time Dollar. Then you have a Time Dollar to spend on having someone do something for you. It's that simple. Yet it also has profound effects. Time Banks change neighborhoods and whole communities. Time Banking is a social change movement in 22 countries and six continents.
