There is no charge to become a member of the website and access to all areas is free.
However I would like to use PayPlans to receive subscriptions for access to a mobile app using the Joomla Role Based Access Control, is it possible to do this with PayPlans?
I assume PayPlans would link a user to the relevant Role (for example Subscriber) when payment is made to the Mobile Subsciption plan?
The mobile app would only allow access to users who have (in this case) the Subscriber Role.
The subscriptions may come from existing members or non-members, is that possible (once a subscription is paid the person would be (or continue to be) a member of the website with (in this example (subscriber access).
