Hello, I'm Materialscientist. I noticed that you made a change to an article, Adina Porter, 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) 22:37, 8 May 2020 (UTC)

Please do not add or change content, as you did at Nunu Nana, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. EN-Jungwon (talk) 14:08, 16 November 2020 (UTC)
