Hello, I'm MarginalCost. An edit that you recently made to Moseley's law seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! MarginalCost (talk) 18:51, 16 June 2020 (UTC)
