Hello, I'm Klilidiplomus. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Extended Backus–Naur Form, 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. Klilidiplomus+Talk 12:26, 11 September 2013 (UTC)
