Can anyone help me with this? Let's say that a person is taking one of my paid educational courses. They are viewing it in Adobe Reader 9.0 or higher. The person decides they want to email this lesson to a friend. They click "File/Attach to email" (or they attach the file from a folder). When the email page opens up, is there a way I can embed a script in the PDF document so this message automatically appears in the body of the email, "WARNING: forwarding this lesson is a violation of our user agreement."
But didn't you try this? : restrict your file with the following opening-password : "forwardingthislessonis aviolationofouruseragreement"
