Hello, I'm Matt294069. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Data mining— because it did not appear constructive. If you would like to experiment, 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. -Animation is developing 05:32, 31 July 2018 (UTC)
