There may be times when all users need to be notified or alerted about an upcoming event such as an upgrade. Such messages can be sent using the alert system.
Open Alert List
From the home page or dashboard, click the Show All button in the Alerts panel.
Add an Alert
Click the Add User Alert button.
Create the System-Wide Alert
From the To list (1), select All. Selecting "All" will make this a system-wide message as opposed to a message to a specific group or user. Enter an expiration date in the Expires After field (2) and the text of the message in the Message box (3). Click Save.
Message is Displayed
All users will see the message scroll in the dashboard header (1) and will also see it in their list of alerts (2).
