  Hello, I'm Amccann421. I noticed that you made one or more changes to an article, Virtual reality, 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! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

Hi. Promotional sources do not serve as reliable sources. We try to limit promotional namedropping. – Thjarkur (talk) 11:33, 8 February 2021 (UTC)Reply
