Knifeforums and Bladeforums have feedback pages (Good, Bad, and Ugly on BF), dedicated to members outlining good/bad experiences they've had with vendors, sellers, individual buyers, etc. It's a nice way of finding out who deserves our business, and who to trust when selling something. Puts it all in one place, too, and allows someone who may have had something negative said about them to defend themselves where everyone can read it. Sometimes things happen, and it might not be the maligned person's fault. Also lets you know who makes contact when things go wrong or right. I think that with the amount of straight razor paraphernalia around, and the rabid dedication of its adherents, it'd be nice to have a quick reference point to go to when you're thinking of buying or selling, without looking through every post on the site.
