Have you guys considered adding a "Pls Remove" tab in the buy/sell forum? I'm a member of another forum and they have a similar volume of items listed, but the main difference is that once the item has sold you can go into the thread options and select a "Pls Remove" button, which flags the post to be removed by moderators. I've found this to be a very nice feature for de-clutterring and maintaining the for sale section. It keeps only those items that are actually for sale listed. Why have hundreds of pages of listings that are either sold or no longer for sale?
