Hi All - I have just taken over the administration of our Totara system so am asking this with limited understanding of the system (I'm making my way through) and hope my question is not too basic, lol. 

We want to update the audiences in the system as they were originally created manually for each course, i.e course = how to walk the dog, audience = how to walk the dog. We have created new audiences based on role and location and want to 'reapply' them to the courses. I can see that if I add a new audience to a course it just adds the extra users on.  

We want to know, if we delete the audiences out of the all the courses and then reapply the new ones we have created based on role and location, what happens to the users that may be included in the new audiences and have completed the training.  Will that completion be included once they are put back into the course in the new audience?
