[http://www.eekim.com/blog/collaboration/tools/networkedtoolsemail.html Eek speaks] about [http://www.freecycle.org/ freecycling]. A wonderful grassroots and entirely nonprofit movement of people who are giving (& getting) stuff for free in their own towns using a simple mailinglist.
Freecyclers have only one rule:
:Everything posted must be free, legal, and appropriate for all ages.
An excellent way to get rid of stuff of value to another but not to you. And reduces waste in the process.
