Hello, I'm Edison. I wanted to let you know that I undid one or more of your recent contributions to Bessemer process 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. Thanks! Edison (talk) 15:56, 11 December 2012 (UTC)
