CMS Made Simple Forums

I am using CMS Made Simple 1.8.1 "Mankara"  and PHP Version 5.2.13.  I am trying to figure out a way to create an interface where if the user would like to download a pdf from my white papers section, they must give their email address before they can download it.  I was thinking about using the Newsletter Made Simple Module and maybe try to create a different response template and user listfor that functionality.  I wasn't sure if there was another solution, possibly another module that I could uset that does this exact functionality.  Anyone else have a solution that may work better? 

You can take a look at FrontEndUsers in combination with CustomContent, Selfregistration and Uploads for the actual download part.

That sounds like it might work.  Thanks for the idea!
