Hello, I'm Lugia2453. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Euler characteristic, 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. Lugia2453 (talk) 21:45, 10 October 2013 (UTC)
