Hello, I'm MadGuy7023. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Portal:Systems science/Intro— 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. MadGuy7023 (talk) 20:47, 16 March 2015 (UTC)
