The Freecycle Newcastle-upon-Tyne group is made up of over 9,000 members. It's a grassroots and entirely nonprofit movement of people who are giving (and getting) stuff for free in their own town. It's all about reuse and keeping good stuff out of landfills. Each local group is moderated by a local volunteer (them's good people). Membership is free and other city areas can be searched for via the website too.
