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 Abstract (summary), 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) 07:31, 23 April 2014 (UTC)
