Hi there, I recently purchased an item from clickbank and the pdf document was protected by some kind of software, think it was called pdf guard or something along them lines. The idea seemed to be to stop people from simply copying your content. Did a quick search on the internet, but the majority of the sites I came across seemed to charge. I was just wondering if anyone could fill me in on what the best way to protect your documents, as I'm thinking about publishing my own product at some point in the future. Thanks in advance.
