Hello, I'm Materialscientist. I noticed that you added or changed content in an article, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 20:36, 13 December 2020 (UTC)

Please do not add original research or novel syntheses of published material to articles as you apparently did to Swinford. Please cite a reliable source for all of your contributions. Thank you. JJP...MASTER![talk to] JJP... master? 20:49, 13 December 2020 (UTC)
