Hello, I'm Reatlas. I wanted to let you know that one or more of your recent contributions to Crystal structure have been undone because they did not appear constructive. If you would like to experiment, you can use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! —  Reatlas  (talk)  08:34, 17 September 2013 (UTC)
