Time Banks

Time Banks are a tool for building community. Time banks involve people on the basis of what they enjoy and can do. They provide the missing ingredient in public services - people's participation - by encouraging time givers of all ages and abilities to deposit their time and get that time back when they want some help themselves.

In addition,  many bartering organizations have begun to develop using a method similar to time bank programing, including OurGoods and Skillshare.
