On your dashboard you will see current Staff Notices. These notices may be updates from Career Central or from Careers Advisers.
You can either click on the "New Staff Notice" button above the notices, or navigate to the "Create Staff Notice" menu item under the "Events/Notices" tab.
Here you can enter a title and body text for your notice, and specify what dates you would like this notice to be visible for (notice will be hidden after the end date).
You can also attach files to your notices, and they will be able to be downloaded from the dashboard.
