Hello, I'm Calvin 1998. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Male contraceptive, 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, Calvin ( t· c) 22:03, 3 March 2013 (UTC)
