The Shinobi Mailbox is a mailing system integrated into the game. It works just like an emailing service and is located at the top right-hand side usually (depends on what template you are using). In the Mailbox, you will notice:
|[ Friend List ]|
|Inbox||Write||Mail Archive||Mail Notepad||Outbox|
Beneath all your messages, you will notice:
|Check All||Delete Checked||Move Checked to Archive||Grab Checked as PDF||Delete All Read|
