Hello, I'm Yintan. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Functional dependency, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.  Yinta n  12:37, 11 June 2013 (UTC)

Please stop. If you continue to vandalize pages by deliberately erasing material as you did with Haigazian University page, you will be blocked from editing Wikipedia. werldwayd (talk) 15:49, 4 May 2015 (UTC)
