What I am looking for is a way to notify learners who should attend a live training and either did not register or registered but did not show up at the previous session. Currently, in the list of learners of the live training, the date of the first session they registered to appears next to their name whether they came or not. Any learner added to the live training does not get notified when the next session is set up with a date. Therefore, unregistered learners or learners who have not attended are not really aware of the next session. How can this be improved ?
