Hello, I'm Duncan. I wanted to let you know that I undid one of your recent contributions, such as the one you made with to University of North Sumatra, 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, —DuncanWhat I Do / What I Say 06:56, 1 March 2013 (UTC)
