November 2012 edit

  Hello, I'm Vrenator. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Cefacetrile, 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, Vrenator talk 11:23, 8 November 2012 (UTC)Reply
