Hello, I'm Materialscientist. I noticed that you made an edit to a biography of a living person, Kristin Cooper, but you didn’t support your changes with a citation to a reliable source. Wikipedia has a strict policy concerning how we write about living people, so please help us keep such articles accurate. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 12:15, 11 October 2020 (UTC)
Please do not add or change content, as you did at Ethel Kennedy, without citing a reliable source. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. Robvanvee 11:25, 30 October 2020 (UTC)
