Every content file in the Content library has a unique URL that lets users view the contents of the file. You can send this URL to other people by e-mail from within Acrobat Connect Pro Central.
Acrobat Connect Pro creates a unique version of the URL for each e-mail recipient. Compared to pasting the URL in an e-mail, using Acrobat Connect Pro Central has these advantages:
You can request that Acrobat Connect Pro send you a return receipt when an e-mail recipient clicks the web link. You can track who viewed the contents because a unique URL was created for each recipient.
Recipients can view the content without having to log in to Acrobat Connect Pro. This is true even if the permissions for the content file in the Content library are not set for public viewing.
