If can't fix issue list items please allow sell unidentified maps in the currency exchange.

If you can't fix the issue where people list items for sale but don't actually sell them, then please at least allow us to sell unidentified maps in the currency exchange. It's really frustrating to click to buy something only for the seller to ignore or not respond. There are also a lot of people who want fixed prices. Please do something about this — it's getting really annoying.
