I'm trying to figure out how to deliver premium content in form of downloadable eBooks or video eCourses for paying members. The challenge I'm having is that if I charge a monthly premium membership fee, what is going to stop someone from going to the location and downloading all of the premium content at once? So I thought of creating a new link/forum for every new eBook (how tedious) but how will I let new members have access to the previously issued content without giving them the entire farm? Is there a way to set this on auto-pilot and deliver one eBook every two weeks but without letting new members get in and download all of the previously issued material? Looking for some type of 'drip' functionality. How's anyone else handling this?
