This mod adds a second location to place MineCraft maps.
The Folder they need to be stored in is the "Maps" folder generated when you first enter the world select screen.
The Maps are not playable from that location.
To play a map press the "Make from Map" button on the world select screen to copy the map from the "Maps" to the "saves" folder.
Proceed to destroy the map or what ever people do on that map.
When done delete the save press the button again and you can blow it up again and again and again...
