Hello, I'm Z0. I noticed that you made a change to an article, Litmus test (politics), 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. The editor  whose username is Z0 09:08, 9 August 2018 (UTC)

Please refrain from making test edits in Wikipedia pages, such as those you made to Gram stain, even if you intend to fix them later. Your edits have been reverted. If you would like to experiment again, please use the sandbox. Thank you. Natureium (talk) 15:34, 14 January 2019 (UTC)
