• Receivers can right-click or shift-left-click the XP bottle to deposit XP.

Admin packages can also include experience without using the admin’s personal XP.

Post Office System

Post Office Boxes are public mailbox access points that can be opened by players.

• Useful for spawn mailrooms, towns, hubs, and servers without Citizens.
• Uses a normal single chest with a sign attached to the front.
• No fence-post base required.
• Admins can register, remove, and view PO Boxes through the GUI.

Dynmap support is optional.

When Dynmap is installed, MailboxGUI can show markers for:

• Player mailboxes
• Post Office boxes
• Post Office NPCs
