Hello, I'm Optakeover. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Category:Periodic phenomena— 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. Optakeover (U)(T)(C) 02:53, 23 April 2016 (UTC)
