User talk:Pandurang nirmal

Welcome to Wikipedia and thank you for your contribution(s). I am glad to see that you are discussing a topic. However, as a general rule, while user talk pages permit a small degree of generaliation, other talk pages are strictly for discussing the topic of their associated main pages and many of them have special instructions on the top. They are not a general discussion forum about unrelated topics. If you have questions or ideas and are not sure where to post them, consider asking at the Teahouse. Thanks.

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 referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 21:18, 10 October 2022 (UTC)
