Hello, I'm Mark Arsten. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Panama Canal, 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, Mark Arsten (talk) 17:29, 6 December 2012 (UTC)
