So, I want to start a big project, a big RPG Server. For this RPG Server I had an Idea, since you are able to print Images on Maps, why not use them as stationery? When you right click a specific block that can be set by an admin, a Sign Menu opens (Dont know if this is possible, if not you should be able to do it with a command) and you can write on your map. Congratulations, now you created a Letter. But what about a mailbox? It should be made of a chest and a fenceblock under it. When someone right clicks it with his letter, it automatically comes into the chest, until the chest is full of course. I don't know if this is possible since im no coder, but if it is possible I and many other people would be glad if someone looks into it.
