User talk:Memory is precious

October 2020
Hello, I'm LauritzT. I noticed that you added or changed content in an article, Polish Operation of the NKVD, 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 the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page.   — Lauritz Thomsen (talk) 09:51, 20 October 2020 (UTC)
