Hello, I'm Astatine-210. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Pfizer, 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, at-210 discovered elements ∞ what am I? 13:05, 13 September 2012 (UTC)
