Hello, I'm Kethrus. An edit that you recently made to Means of control devices and systems seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! -- Kethrus ///  Talk To Me   14:52, 18 October 2014 (UTC)
