Hello, I'm TheImaCow. I noticed that you added or changed content in an article, Berlin Conference, 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.   --TheImaCow (talk) 16:08, 21 November 2021 (UTC)
