I've always left feedback by going back to the ad (or any other classified by that seller) and clicking on their name in the info area. That should take you to a profile thing that lets you open Feedback and there is a pushbutton for good-bad-ugly or whatever, plus a dialog box for praise-singers to use. I always leave feedback about sellers, found only one about me (as a buyer). Given that our Club here is light-years ahead of The Bobtail Nag (or did somebody bet on the Bay?) I always try to jolly things along in lieu of buying my counterparty in the transaction a beer or some other uplifting beverage.--alfredian
