Hi Calvin,

A program is a structured collection of courses, as outlined here, which can be presented to a specific Audience, group or individual Learners.

A program can consist of one, or multiple courses.

Program messaging is an integral part of the program functionality; its possible to set multiple daily Course set due or Program due messages.

However the Due-date messaging is predicated on course completion, so if the activities you want reminders to go out for don't trigger course completion then it won't work, if that's the case it might be worthwhile investigating Austen's Catalyst plugin - we don't support 3rd Party plugins, but Catalyst has been working very closely with Totara for over six years.

Let me know if you have any other questions or if I haven't been clear.

cheers,

George.
