Hello, and welcome to Wikipedia. Although everyone is invited to contribute, at least one of your recent edits, such as the one you made to Kent State shootings, did not appear to be constructive and has been reverted or removed. Please use the sandbox for any test edits you would like to make, and read the welcome page to learn more about contributing constructively to this encyclopedia. The reverted edit can be found [//en.wikipedia.org/w/index.php?diff=491789279 here]. Yunshui 雲&zwj;水 12:39, 10 May 2012 (UTC)

Recent edit to Norm Macdonald
Hello. I noticed that you made an edit to a biography of a living person (Norm Macdonald), but that you didn't support your changes with a citation to a reliable source. Wikipedia has a strict policy concerning how we write about living people, so please help us keep such articles accurate. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you! Materialscientist (talk) 12:44, 13 August 2015 (UTC)

It may not have been your intention, but one of your edits, specifically one that you made on Chelsea Manning, may have been a change that some consider controversial. Due to this, your edits may have been reverted. When making possibly controversial changes, it is good practice to first discuss your edit on the article's talk page before making it, to gain consensus over whether or not to include the text, phrasing, etc. If you believe that the information you added was correct, please initiate that discussion. Thank you. – S. Rich (talk) 02:46, 23 May 2021 (UTC)
