Hello, I'm Materialscientist. I noticed that you made a change to an article, Brian Callahan, 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) 08:02, 31 January 2023 (UTC)

Please do not add unreferenced or poorly referenced information, especially if controversial, to articles or any other page on Wikipedia about living persons, as you did with this edit to Brian Callahan. Thank you. Materialscientist (talk) 08:03, 31 January 2023 (UTC)
