Reserve a World   Reserve a world is available for groups who want to reserve a world. This would be purchased by a group like a school who wanted to allow a class to play in a world dedicated to their students only. The reason for this is that the school can moderate the dedicated game and control who has access to the game, thereby ensuring the type of experience they are desiring to create. A reserved world still uses basic and advanced game rules for access. So reserving a world allows complete use of the basic game under the same rules as the publicly available worlds with the added benefit of controlled access. A world gets reserved from the time that the purchase is made, and this remains good for a specified length of time. When the world is reserved an access code is issued that is used to restrict access to only those who have the proper access code.
