As the creator of a course, is it possible to limit the subscription to a published course to some given users (via password or whatever)?
As we have been trying to create open community, we do not offer creating private courses and limit the subscription to some chosen users. Nevertheless, this option is available in B2B cooperation with supermemo.net. Still, the point of supermemo.net is to create a community with no limits of sharing and using courses made by other users - limiting it would not have a good influence on our community.
