You can send notifications/messages to staff, which can (optionally) include a request to start a specific course.
Hover over Notifications in the menu at the top of the page and select Send Notifications.
From here, you can type a message and select a specific course for them to complete.
Note: you do not have to select a course for them to complete if you only want to send them a message (for example, a reminder to complete any outstanding courses before a deadline).
You can send the notification to a single user, a group of users, or all users. Once you have filled out the form and selected the users, click Send Notification at the bottom of the form.
