You can get to this from the Home dashboard, and also "My Campus". From the Home dashboard:
From "My Campus" dashboard
Here you can set the campuses and subjects you want to see and hear about. What you set here decides which tiles appear on your "My Campus" dashboard and which items you see in "News and Events"
You have to log off and on again to see it take effect, and then give it a while to synch up to the Cloud.
Setting up Your Preferences
Re-arrange and change the colours of your dashboards:
1. On the top right of the header, click "Personalise"
2. You can now drag and drop the tiles around to place them where you like
3. Click the cog wheel on any tile and a new panel opens - here you can change colours:
Set your Campus and News preferences:
Use the My Preferences or My Campus tiles to set your preferences.
This brings up a new panel where you can tick and untick items.
The Campus Locations group affects which tiles you see on My Campus, and all of the boxes affect your News and Eevnts feeds.
Remember you'll see them work only next time you log in to the Hub, as they need to synch through to the Cloud.
