Hello, I'm Ryan032. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Birkhoff interpolation, 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.  -Ryan  06:36, 12 August 2013 (UTC)
