Adding activity locks
Overview of Activity Locking
Activity Locking is a type of conditional activity in Moodle. It is not part of the standard Moodle and all flavors requires sepecial installation. Various flavors can be found at the Activity Locking MoodleDoc page.
Please be patient, there are several versions of Activity Locking being developed that have different goals and approaches. These examples happen to come from an Activity Locking 2.1 flavored branch developed for Moodle version 1.6, sometimes called ActivityLockingWithHide-1.6 Other versions may also appear on this page. Finally (there really is never any finally), I am most familar with Lesson Activities, so my initial screen shots will concern this kind of activity. I am trying to keep the new Moodle teacher in mind as I write. --Chris collman 2 05:09, 27 June 2006 (WST)
