Here’s a quick video by Mary Cooch (@Moodlefairy) of a new feature in Moodle 2.4 I had not seen. It’s the ability to restrict access of activities in Moodle by information in the user profile fields. Students could be grouped in new ways and access restricted based on groupings at a site wide level. Alternatively, based on a user’s country information might be changes or augmented to help them through the course.
