How to deliver digital files from my site without making them public?
I have an opt in page on my Wordpress site that is linked to an auto-responder (Aweber). I'd like Aweber to send a welcome email with a link to free PDF download(s). How do I set up the delivery on my IMH site where the content download link is only available to those receiving the link from the opt in (not public)? Where do I store the PDF files to be downloaded?
