The Messages tab shows the messages connected to your administrator account. It is separated into three sections: Notifications, Sent Messages, and Email Archive.
Notifications - Log of system notifications sent to your account, including submissions, review assignments, and application updates. Click on the subject title to view the notification. Administrators can choose which automated competition notifications they receive when they create or edit competitions (found in the Notifications menu of a competition).
Sent Messages - A record of messages you sent to other users as the Main Owner of a competition. Click on the subject title to view the message.
Email Archive - You can archive messages from either of the first two sections after you view them by selecting the check box next to them and then clicking the Archive Checked button. These messages are then listed in the Email Archive section.
