When I'm developing new content, I like to be able to email out a link to relevant groups for feedback. I want to be able to make it so that the course doesn't show up in the course listings, but is accessible to anyone with the link. Is that possible? So far my only options seem to be either making the course visible to everyone and plastering it with "DRAFT CONTENT" warnings, or giving special permissions to every potential reviewer.
You could just add a password to the course and then give that to your reviewers and no-one else would be able to enter it.
