Hello, I'm Materialscientist. I noticed that you made a change to an article, Mount Diablo, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 06:57, 18 March 2017 (UTC)

Hello, I'm Crystallizedcarbon. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Franklin High School (Elk Grove, California)— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. Crystallizedcarbon (talk) 18:36, 28 August 2019 (UTC)
