Hello, I'm Eeekster. An edit that you recently made to Vitamin C seemed to be a test and has been removed. If you want more practice editing, 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! Eeekster (talk) 02:33, 10 November 2015 (UTC)
Hello, I'm Materialscientist. I noticed that you made a change to an article, 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.
