This addon allows you to require a user to tweet a message if they want to download a file. This is an excellent way to increase interest in your site on social networks. The user likes the arrangement because they don't have to pay to access a downloadable file, and you like it because it creates more visitors for your site. The downloadable file could be an ebook, image, or anything else! 

If you want a single tweet to provide access to several files, simply set the text the user has to tweet to be the same on each block.
