Hello, I'm Gogo Dodo. I noticed that you made a change to an article, Soviet submarine K-129 (1960), 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. -- Gogo Dodo (talk) 23:55, 29 December 2016 (UTC)


 * Re your message: While you have professional view on the matter that few have, Wikipedia article contents must only contain statements that can be verified from reliable, published sources. You would need to provide citations from a reliable, published source to include a new theory on K-129. -- Gogo Dodo (talk) 06:04, 3 January 2017 (UTC)
