I'm looking for an installable or hosted software (service) to handle the process of public users subscribing to the Magazine and receiving the PDF automatically upon an admin upload the new one. The system will have to:
- handle the money part (PayPal&Co. are OK)
- let user buy old issues of the Magazine
- warn user on subscription expiring, etc.
PDF stamping and WordPress integration (user credential sharing, page access of subriscrebed goods, etc) will be a big plus.
