Hello, I'm Rdp060707. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Cis–trans isomerism—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. Rdp060707&#124;talk 02:50, 19 April 2021 (UTC)
