I just saw a lot of users in the list that are not our students and who we have not created as users. They can't enrol or view any of the courses because they're blocked, but then I'm not sure why and how they became users?
Is this someone trying to get into our page? How did they activate themselves as users? Is there any option which allows me (meaning the school coordinators) to be the only one able to create users or prevent people from doing it?
