Hello, I'm MathXplore. An edit that you recently made to File talk:Operating system placement (software).svg seemed to be a test and has been reverted. 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!
