Automatic alerting teachers who omitted to fill out the curriculum in the class register

A notification can be sent to teachers who omitted to fill out the curriculum in the class register. That way the teachers ate alerted to fill the curriculum out.
First, set the period for filling out the curriculum to 2 days for example. The teachers' calendar in the class register turns red in days with lacking curriculum.
Tick the "Notify teachers" box.

The teacher receives a notification containing information about the earliest lacking curriculum, the number of lessons lacking curriculum and the relevant classes.

If the teacher does not fill out the curriculum, the notification is sent again in a couple of days.
