Your edits to Digital watermarking
Hello, I'm Petrb. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Digital watermarking, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Petrb (talk) 13:57, 26 September 2013 (UTC)
