Hello, I'm Walter Görlitz. I noticed that you made a change to an article, The Ongoing Concept, 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.

Please do not add or change content, as you did at The Ongoing Concept, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. ''The dates are not source. That's the problem.''
