How do you know if you have unread messages?
On the "root" page, your homepage:
The number of unread messages is displayed in red next to each sphere:

On other pages
- The total number of unread messages is indicated in the red dot above "My spheres" (in the header, top left)
- In the menu, after clicking on "My spheres", the red dots next to the spheres indicate the number of unread messages in each individual sphere
Consult your new messages in a sphere
To view new messages, go to the spheres where they have been shared.
Unread messages can be easily identified: the text is in bold and a small red dot is displayed to the left. Messages will automatically switch to "read messages" as soon as you hover your mouse over them.
