Hello, I'm Materialscientist. I noticed that you made a change to an article, Czechville, Wisconsin, 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) 16:39, 4 January 2021 (UTC)

Please stop your disruptive editing. If you continue to add unsourced or poorly sourced content, as you did at Karl Ferdinand Braun, you may be blocked from editing. -- Jezebel's Ponyo bons mots 19:46, 7 January 2021 (UTC)
