Particularly would be good as a dotnetnuke module (4.3.x). Ideally the use case I’m after would go like

1) User browsers to my minicourse page on my dotnetnuke site.

2) Users enters email address and Name in form and presses submit

3) System associates user with a particular course that is n days long and is scheduled to be sent at a particular time each day.

4) at n intervals Scheduler checks for course messages to be send, if there are any matching courses it goes through the list and sends part x of the course via email (whatever the user is up to).

5) system updates the minicourse settings to mark that a particular has been send a particular part of a particular course so tomorrow they will receive the next edition or if the course has finished they will receive nothing.

6) Repeat 4-5 each day

If any one know anything, dotnetnuke or not, I would be very appreciative.

Cheers
