I have a question about how best to set up our enrolment. Right now we are only showing tutorial video pages and we'd like to automate the enrolment (so we don't have to add each person manually). At the same time we don't want to have "self enrolment" as the people we email could share the URL link around to anyone. Is there a way to create automated enrolment whilst having the control of who enrols (ie. if we email a CEO of a company who we have invited onto the course (he would need to self enrol) and he wants his staff to be on our course (who would then need to self enrol to see the videos) how could we stop anyone outside of that company from enrolling? Is there anything that could help us achieve this?
