There was some discussion about having a buyer/seller feedback system, so thought I'd move the discussion here.
I agree that such a system would be a nice to have, but it is something else that needs to be installed and maintained. Even a thread is difficult unless someone goes through the thread and keeps track of things, and even then it can result in a lot of bickering... and the moderators don't get paid enough to try and mediate disputes.
So what I suggest is using something that already exists:
http://www.heatware.com
The buyer and seller each sign up there and each transaction gets logged, with positive, neutral, or negative, details of transaction, etc etc.
Keeps all the details in one place, and is far more robust than anything we could ever do.
Frequent buyers and sellers can post their heatware in their posts, or potential buyers and sellers can request a link to the person's heatware so they can look at it.
Thoughts?
