Caveat Emptor... buyer beware...

I do have an idea though, for the noobs that dont know so much about the buying situation, perhaps have an eBay style rating next to the traders name, rather than having it behind a link that one needs to follow and read comments which could potentially be very long...

Lot of work to set up, but a more ready deterrent i suppose... but then you are really moving the focus of the site in a direction which is completely obvious by Wyn's commentary that he doesnt want to take it... its a community not a sale site...

Difficult balance i suppose... then again, the issue will be more prevalent in the private sellers rather than traders... then where do you draw the line, does everyone have a visible percentage?
