Hello, I'm MelbourneStar. I wanted to let you know that I undid one or more of your recent contributions to Piperazine 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. -- MST  ☆  R   (Merry Christmas!) 05:54, 16 December 2012 (UTC)
