Hello, I'm Marek69. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Logic gate, 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, Marek  . 69  talk 08:32, 8 May 2013 (UTC)
