Hello, and thank you for your recent contributions. I appreciate the effort you made for our project, but unfortunately I had to undo your edits 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! StudiesWorld (talk) 20:09, 23 June 2019 (UTC)
