Yep. Some people that are self-posting would bump their posting again here, repeatedly, if the item didn't sell.
Better would be to have a separate "for sales forum" discussion thread if there is a real need for it or interest in it. Then those that are interested in it could subscribe to it, too. No need to combine it into this one
yep keep your damn classifieds in the damn classifieds section and don't bump unless you've waited a decent amount of time.
