Hi.
after I bought an ebook on amazon I passed out to a friend a pdf copy of the awz file I had previously de-drmd and converted to pdf with calibre. I am only now thinking that this was not a good idea. could there be a watermark in the pdf that would trace the file back to my amazon account? this was not done with commercial intent, but I am a bit afraid that this person could pass this pdf on to someone else and so on. I thank you in advance and hope I have not done something too stupid.
