Totara Learn Open Discussions

This is how I have done it in the past, Tom. A more manual way to do it, which has been a preference, is to have a 'not completed course xxxx' and use the bulk user action 'Send message' to that audience. Great when you don't need to message about a lot of courses. I just popped a reminder in my calendar with the audience id, this is needed as the filter, and any links I needed to add to the message. Not automated, but gives you great control, as you can add/remove people to message manually without changing the audience. Other customers have just added the course to a program too and used the messaging functionality there.
