Hello, I'm O.Koslowski. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Convergent boundary, 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, O.Koslowski (talk) 18:52, 14 November 2012 (UTC)
