Hello, I'm Jim1138. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Electrical engineering, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, Jim1138 (talk) 06:01, 2 September 2012 (UTC)

Hello, I'm Materialscientist. I noticed that you made a change to an article, Katti Batti, 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) 14:05, 5 September 2021 (UTC)

Please do not add or change content, as you did at Katti Batti, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article.   Pachu Kannan (talk) 15:06, 5 September 2021 (UTC)
