I'm sure I saw on some promotional material for membermouse that you offer a method for pdf/document download protection. However, I can't seem to find any information on it now.
Does MM have any way to protect pdf file downloads with licences etc?
Since MemberMouse protects WordPress pages and posts, you will usually need to use another plugin for protecting the linked files on those pages and/or posts.
This article explains how you could do that: How can I protect links to documents like pdf's?
