add a marketplace block
it is a block that can be bought by the major of a town.
it costs like 500 to 1000 gold.
the major can place it in his town and every citizen can use it.
when you want to sell something, you just place the item in the block and set the price. then other people can buy the items and you will automaticly get a message. the gold will then be in the block. you can see the items from your town and other people's town.
it could be a possible way to get items that normally would cost platinum for gold. it would also be a way to get rid of items you don't want or just another way to earn gold
