Hello, I'm Piandcompany. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Piperidine, 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, Piandcompany (talk) 01:31, 28 November 2012 (UTC)
