Want/Have

It would be a great community-building feature to have "wants" and "haves". we can have "objectives", but that is different. Want's and Have's should be able to be categorized (personal, product, real estate, etc) and searchable.  There should be some way to show when a match is made, and then score it so you can see who is the best benefactor and who is the biggest leach.

(I tried to search the forums for this topic here, but the search on the top right to search all didn't seem to work for me in firefox. sorry if i have created a double post)
