Notifications from Absalon
In global navigation, click on "account"
Click on "Notifications" and make sure the "account" option is displayed.
Go further down and turn ”administrative notifications” off by clicking on the ”notifications off” icon.
If your Absalon is in Danish, it is the "administrative meddelelser" you need to turn off.
By adjusting the settings you will no longer receive notifications when a new user is manually added to the course.
