Hello, I'm Reatlas. I wanted to let you know that I undid one or more of your recent contributions to Callback (computer programming) because it did not appear constructive. If you would like to experiment, you can use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. —  Reatlas  (talk)  13:41, 9 October 2013 (UTC)
