Hi John,

I've had a quick look and these are the things I found:

Report Builder - to email scheduled reports

Totara Messages - to periodically delete old alerts/tasks

Course completion - to update completion records

Competency - to aggregate competency proficiencies

Reminder - to send reminder emails

Other than that there's all the usual Moodle cron activities, but the list above covers what we've added in Totara.
