A splendid idea! ReUse Connection is not live yet but according to the info they have up now, it will be in the next few months. I predict it's going to be big! In the meantime, you can follow them on facebook.
From the site:
"Have you ever wanted to get rid of something but didn't want to throw it away...and yet not known what to do with it? Come visit ReUse Connection and see what people around the world do with everything from old shoes to chemicals to anything you can imagine.
