Make it so that when you hit "Marketplace" it'd bring up a page where it asked if you wanted to create a shop or search shops when you created a shop make it a form like the post making form So instead of subject "Shop Name" and where you would put the message you could put the description, then you could select whether you wanted people to bet on your items or just buy them at a set price. You'd only be able to select items that were in your inventory. This would also give a use to botstract as you could make it the currency for these new personal shops.
