ShadowHaven has several ways you can earn money besides voting and getting a job!
Do you like to gamble? Buy some lottery tickets using /lotto buy (the number of tickets you wish to purchase). Lotto tickets are $50 each and it is winner takes all.
Have something you want to sell to another player? Sell it in the auction house! Looking for something to buy? Check out what other players are auctioning.
/ah - accesses the auction house gui
/ah sell (price) - auctions the item in your hand
You can set up shops to sell items. If a town sets up a shop, the mayor or comayor may request a warp to their shopping area, but only one shop warp per town.
Shops may only be created on Shop plots. (/plot set shop)
Hold the item you want to sell in your hand and do /pshop create (number to sell) (cost to buy) (cost to sell)
You will then be asked to punch the chest that you would like to use as a shop.
Using the trading plugin is a safe way to trade with other players, and not get scammed. Type /trade (playername) to send a trade request with someone. When they accept you can add in items from your inventory and/or money using the gold (nuggets add/remove $1 at a time, ingots $10, and blocks $100). When you are happy with what you are offering click the green wool, after both players have clicked the green wool you will have another chance to accept the final trade.
