For further information on the plugin, see the plugin's help file here. The plugin has 2 styles of downloads and these can be changed by user. The 'PDF Downloader' style allows users to download just the PDF file and also allows them to see the contents of the PDF, such as a table of contents. The 'PDF Encryption' style allows users to store the PDF to be decrypted later and will not affect the user's experience. The Plugin can also be installed multiple times, using different settings for each 'downloading' user. Users will not be able to download the PDF without first being prompted to use the Downloader setting, which will only work on WordPress. After choosing their mode of download, the user is redirected to download.php, which then has the PDF downloader, or the encryption setting, which will encrypt the PDF.
