On the Administrators "course settings" page, the admin can set site-wide defaults for new courses. One setting which is NOT included is "course enrollable: No / Yes / date range"
We greatly need this setting to exist on the Adminstrator's course settings page, as the only way we have found to change this site wide is to change the code, which since we are hosted with Moodlerooms, we cannot.
Actually, for that matter, why not include ALL of the course settings there? That way the admin can set up the defaults for all of them?
