Your inbox is where you view the messages sent to you by other users of the game. The messages, called PMs, or Private Messages, are set up fairly simply. The user who you are talking with, the subject line of the message, and the date and time of the last reply are included.Pms and Inbox Bold messages indicate an unread response, and they are in order of newest to oldest. Messages with no player mentioned are clan Mass PMs(or certain confirmations from the public events). Messages cannot exceed 500 characters.
To the right of the New message Button is the "Block someone" button. This can be used to block annoying people, or people who are trying to start a flame war. Using this button can prevent reports and keep you happy by not being banned for fighting back at the flamer.
