Freecycle

"This CNN article looks at Freecycle.org and says it "is popular with a new breed of tech-savvy greens who are putting their unwanted goods up for bid on the Web, instead of throwing them in the trash.What makes Freecycle unique, though, is that everything up for grabs on the site is free".Further,"the site has 1.6 million members from more than over 50 countries"."
