Hello, I'm Dan Koehl. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Information Systems/Hardware, 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. Dan Koehl (discuss • contribs) 16:19, 8 October 2018 (UTC)
