Hi,
I have a message board where some of my users post items for sale. What I want to do is, have a section where the 'sellers' can enter their name and then the 'buyers' can leave feedback on them. To let others know how the sale went. Maybe let them rate the seller, and leave a comment. Something similar to how ebay has the feedback of users.

I've been looking for something like this, but haven't been able to find it. So I was hoping maybe some of you guys have seen something like this.

Thanks
Chris.
