Hello and welcome! I edit Wikipedia too, under the username Metricopolus. Wikipedia is written by people like you and me, so thank you for taking the time to participate. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Atomic mass with this edit, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions about editing, you can leave me a message on my talk page. Thanks! Metricopolus (talk) 07:40, 30 November 2011 (UTC)
