I know that this has been asked before, but I wanted to check if there has been any progress on adding a feature that would make it possible to limit access to a given course to those that have completed another course. I know that the course prerequisites feature does not actually do this currently. I saw that one method was to use an Enrollment Key that is in the prerequisite course and revealed only upon its completion, but is there another solution, either current or upcoming?
I am still using the latest of Moodle 2.6, since I am running Moodle on a server that has to be on 5.3 (so Drupal 6 can continue to run properly).
