PayPal for Free Plugin & Subscription Duration

Hello,

1) I just want to make sure that the video instructions were all that I need to do in order to take payments with the plugin. I have entered my PayPal email in the settings of the Paid Member Subscriptions section however, isn’t there normally an API that I need to register and link? Is there anything else that I need to do?

2) Additionally, When I am setting the subscriptions for the paid for option is gives me the option to set the duration for a certain amount of days or months (maybe weeks too). My question about this is is there not an option where they can pay month to month without dedicating themselves to 12 months (for instance)?

And then when the 12 months is up they will need to go back in and re-register with a new registration name and email if they want the paid subscription to continue?

If so is there a way that the subscriber can cancel their subscription in the middle of the 12 months if they should decide?

Thank you
