Roles and permissions

Hi there,

I would like to use Moodle for internal, organizational purposes for small groups of 20 people or less. However, I do not want the titles of the courses displayed to everyone who logs in. I want the title to only be displayed to those who are enrolled. For instance, I want to have one small unit of my organization be able to see and use this course (in actuality, just the questionnaire), and have it be invisible to everyone else who is not authorized to use it.

Any ideas on how I can accomplish this? I'm using Moodle ver 1.9.5.

Many thanks,
PL
