Membership Pro is a powerful, features rich, easy to use Joomla membership/ subscription extension. It allows you to create and sell subscription plans, allows members subscribe for these plans and give them access to restricted resources on your Joomla site.
Membership Pro can easily restrict access to Edocman by dynamically adding and removing users from User Groups based on the subscriber's membership plan.
Example
Let's create a membership that grants access to premium documents in Edocman.
Edocman
Create a Premium user group and define which categories or documents can be accessed by this User Group.
Membership Pro
Using the Joomla Groups plugin in Membership Pro users that subscribe to the Premium membership plan will automatically be added to the Premium user group. Resulting in access to the Edocman categories and documents.
Once their subscription expires they will be removed from the Premium user group and added to the Public user group.
