Chestshop is used to buy and sell items to and from other players.
The money of Stalgath is called Parons. When you first join you will get 20 Parons. To check your balance type /money, to pay a player type /money pay (playername) (amount). To use a chestshop all you need is either money or the item to sell. To sell you need to hold the item in your hand and left click on the shop, if the seller has enough money the goods will be sent to the chest and you will receive your money. To buy you need to right click on the sign, money will be sent to the seller and you will get the items. If you want to make your own chestshop you need to put in a request saying you have the money, 100 Parons, and would like to create a chestshop. A moderator will come to you and work out how the chestshop works and set it up for you.
Edit: Dyes and colored wool cannot be sold in shops until I figure out how. If you know how, please message me.
