The Freecycle Network™ is made up of many individual groups across the globe. It's a grassroots and entirely nonprofit movement of people who are giving (& getting) stuff for free in their own towns. Each local group is moderated by a local volunteer (them's good people). Membership is free. Can't find a group near you? You might want to consider starting one. Have fun!
