Course subscription policy: courses have different subscription policies but these are not general rules instead they are related to a specific course. Available subscription policies are:

• Self Subscription
• Moderated self subscription
• Subscription by the administrators
• Related to the approvation activity this can be done by the super administrator or the administrator with the appropriate permission.
  

Bounded courses and course catalog: Since the 3.0 version, DoceboLMS has inserted the Bounded Course and Course catalog functions.
Bounded courses are a list of courses sequenced that can be considered in a university environment as “study plans”, inside the same list can exist locked courses that can be viewed only when you finish other “non locked” courses..

A catalog is a group of single courses and bounded courses grouped in a logical box, in an advanced management environment admins can enable or disable catalog visibility to different user groups..
