User talk:Yugo saputro

November 2014
Hello, I'm Avono. I wanted to let you know that I undid one of your recent contributions —the one you made with this edit to Category:Book formats— 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. Avono (talk) 14:59, 11 November 2014 (UTC)
