Trade with other players!
How to use
You do not have to use any command or type anything. To trade with another player, you just right click the user and the trade request is sent. The other player can then accept the trade request by right clicking on you. Once the trade has been initiated, A GUI trade window will pop up. Your trade side is on the left, there items are on the right. Once you agree to the items in the window, you accept the trade by clicking the green wool block.
Okay, there are a few commands. But they are completely optional.
|/trade [playername]||Requests the named player|
|/trade accept [playername]||Accepts request of named player|
|/trade refuse [playername]||Refuses request of named player|
