Hello, I'm Rubbish computer. An edit you recently made to Fixed exchange-rate system seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you.
