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 for now, but if you'd like to include a citation and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 22:26, 13 December 2012 (UTC)

Please stop your disruptive editing. If you continue to blank out or remove portions of page content, templates, or other materials from Wikipedia, as you did at Central and Eastern Europe, you may be blocked from editing. Thank you. Yopie (talk) 00:40, 21 April 2015 (UTC)

Welcome to Wikipedia. We welcome and appreciate your contributions, but we cannot accept original research. Original research refers to material—such as facts, allegations, and ideas—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. Thank you. Yopie (talk) 15:35, 9 May 2015 (UTC)
