User talk:Rex Alwyn

Hello, I'm Materialscientist. I noticed that you made an edit to a biography of a living person, but that you didn’t support your changes with a citation to a reliable source. 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) 22:35, 3 January 2013 (UTC)
