User talk:Sukumaru

Hello, I'm Materialscientist. I wanted to let you know that I undid one or more of your recent contributions to Uranium-238 because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! Materialscientist (talk) 07:13, 11 March 2013 (UTC)
