Hello, I'm Alex Cohn. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Archimedes' screw— 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. Alex Cohn (let's chat!) 21:21, 17 October 2018 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did at Dance Dance Revolution. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Allopathie (talk) 23:40, 31 January 2019 (UTC)
