There, you can see two possible locations for the post office.
Post office is a building where players can leave messages to another player using chests. Ideally, this should be next to the spawn building for easy access. However, due to concerns about lagging out the spawn again, we need to keep it many blocks away from the spawn.
The map linked above above shows two possible locations of the post office. Where should we build it? If you have any ideas for the position of the post office, feel free to suggest one below or right on the map.
