# set_enrolment_method

Change an enrolment method with its form, by its id or the course's first of a type (methodType "self": added when the course has none and Moodle offers it): turn it on or off, its key, dates, role, limit and welcome message. Only what's given changes. Returns the method afterwards (never the key). Opens or closes the course to people: confirm with the person first.
