Adding a Notification
Notifications are different from announcements, in that they are only shown in the member center above the navigation and content area and run like a ticker scrolling through the number of notifications. You can adjust the date range for how long each notification should be running for as well as the content and hyperlink for the notification.
Head to Website Management >> Notifications and click the plus button to add a new notification. Enter in the start date, end date and the message you want to display.
