Replying to A Suggestion for the Site

I Don't know if this has ever been mentioned before but I think it would be nice to create a section in every members profile for other members to leave positive or negative feed back after a sale, similar to how it is done on ebay.  The Karma system is nice, but you cannot tell if someone has good karma as a result of honest buying/selling or from posting helpful information in the forums and vice versa.  The good buyer/seller list is also nice in the ski equipment forum but it could quite frustrating and time consuming to sort through 20+ pages looking for a member name.  It would be cool for example if you were about to buy someones skis that were for sale on NS, click on their profile and you can find a section where other members have briefly reviewed their selling/buying tactics.  Ex: you see 10 people have commented about a member as a HONEST SELLER, GOOD COMMUNICATION, FAST SHIPMENT, EXCELLENT PRICE ETC (hint: buy the skis) and for others you may see THIS GUY STRAIGHT UP RIPPED ME THE FUCK OFF (hint: don't buy the skis)  I'm not suggesting a carbon copy of ebay's system on NS, but just some system in every members profile that is a fast, simple, and efficent way of informing users of a members buying/selling reputation.
