If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help Desk. Thanks. Serols (talk) 14:40, 8 November 2018 (UTC)

Hello, I'm Materialscientist. I noticed that you made a change to an article, G. R. Gopinath, 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) 09:01, 13 November 2020 (UTC)
