Hello, I'm Orphan Wiki. I wanted to let you know that I undid one of your recent contributions —the one you made with this edit to Mohs scale of mineral hardness— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Orphan Wiki 01:05, 12 January 2015 (UTC)
