How/where
OK tried that. It lets you report the sale only if you declare how much it sold for. Then it takers you to another page, but still don't see anywhere to leave any feedback on the sale, which is all I really wanted.
I know someone left feedback on me that said "good guy to deal with", but don't remember how or where they did it. Surely you don't have to be a "friend" to find it on the profile?
I would think RJ would want you to be able to see a sellers history of satisfied or dissatisfied buyers easily on any ad.
