Enrolment

I changed Authenticated Users role to allow them to view a course because I want to make the courses viewable by anyone logging into moodle.

However no longer can a user explicitly enrol themselves for a course. Before making above change, if a user tried to access a course, they would have been presented with a form to say "Yes" or "No" to enroling for a course.

How can I allow a user to explicitly enroll themselves in a course. I don't want to have to enroll them manually as admin.


Thanks much in advance.
