Hello, I'm Pinethicket. I wanted to let you know that I undid one or more of your recent contributions to History of computer science because it did not appear constructive. If you would like to experiment, please 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. Thanks!
