Hello, I'm Materialscientist. I noticed that you made a change to an article, YoWorld, 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) 02:34, 4 June 2020 (UTC)

Please do not add original research or novel syntheses of published material to articles as you apparently did to YoWorld. Please cite a reliable source for all of your contributions. Thank you. Materialscientist (talk) 02:38, 4 June 2020 (UTC)
