I've suggested some changes that I think benefit everyone.
1. Install an autobump feature. Set it to every 72 hours.
2. Anyone who wants to pay 2 dollars per listing will receive an autobump every 24 hours. Up to a predetermined time period like 30-60 or 90 days.
3. Those who list or regularly have more than 5 cues a month need to register as a dealer. AZ has the right to designate you a dealer as well based on your history in that section. There should be a nice dealer package that gives them autobumps every 24 hours for an unlimited amount of time for a reasonable monthly or annual fee.
4. There should be a small team of mods for that section. Once an item has sold the thread is locked. Not removed.
Probably a few other smaller changes would help as well. The current state of things, although well meaning, isn't a good solution.
