Don't remember this being raised before, but why don't we introduce an ebay-style feedback and rating system for the classifieds?
Scanning through a couple of recent threads where people were complaining about not being happy with their purchase, and noting that some people now seem to be using the forum purely for selling stuff rather than being part of the STW community, and having sold quite a few bits on here recently, making an effort to be a decent seller, wouldn't it make sense for people to click on a seller/purchaser's profile to see feedback from previous trades and maybe a score out of 10?
A good way of spotting the honest guys and outing the dodgy ones, no?
