Hello, I'm Gilliam. An edit that you recently made to Data acquisition seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! – Gilliam (talk) 09:07, 22 June 2015 (UTC)
