Hello, I'm JimVC3. I wanted to let you know that I undid one or more of your recent contributions to Computer engineering 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!

If you are an IP user, you may create an account or log in to avoid future confusion with other IP users. Registering also hides your IP address.
