Hello, and thank you for your recent contributions. I appreciate the effort you made for our project, but unfortunately I had to undo your edit(s) because I believe the article was better before you made that change. Feel free to contact me directly if you have any questions. Thank you! Technopat (talk) 11:03, 15 June 2013 (UTC)
