Hello, I'm Optakeover. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Bayes classifier— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

Hello, I'm DVdm. I noticed that you added or changed content in an article, Scale factor (cosmology), 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. DVdm (talk) 16:10, 19 December 2021 (UTC)
