Hello, I'm Robertsky. I noticed that you added or changed content in an article, List of major crimes in Singapore, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. robertsky (talk) 05:25, 29 January 2020 (UTC)

Please do not add or change content, as you did at Berkeley High School (California), without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. John from Idegon (talk) 03:59, 23 February 2020 (UTC)
