Hello, I'm Materialscientist. I noticed that you made an edit concerning content related to a living person on Øystein Pettersen , but that you didn’t support your changes with a citation to a reliable source, so I removed it. Wikipedia has a strict policy concerning how we write about living people, so please help us keep such articles accurate. 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) 09:56, 22 February 2014 (UTC)
