Name: Bazaar

Reasoning: Constantly maintaining a guild bank with a large number of items is a strain on guild officers who's time could be spent doing other things. Perhaps, on occasion, even playing. This is not meant to replace the guild bank or guild items module, but to supplement it.

Implementation: Users can add items to the Bazaar with or without a price. The items then stay in the bazaar until removed by the user or the listing expires after a set amount of time. Once another player expresses interest in the item the shelf life is (optionally) shortened to only a few days. If only one player is interested the item is given/sold to them. If multiple people are then the item can be given away or sold at the poster's discretion, given to the player with the most raid points, raffled, or auctioned.

you should ask nyt about his item bank module
