Hello, I'm Wtmitchell. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Adder (electronics)— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks.

- If this is a shared IP address, and you did not make the edits referred to above, consider creating an account for yourself or logging in with an existing account so that you can avoid further irrelevant notices.
Please refrain from making unconstructive edits to Wikipedia, as you did with this edit to Adder (electronics). Your edits appear to be vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. —MelbourneStar☆talk 09:56, 27 August 2019 (UTC)

edit Hello. This is a message to let you know that one or more of your recent contributions, such as the edit you made to Bresenham's line algorithm, did not appear constructive and has been reverted. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. Thank you.
