Hello, I'm Ainlina. I noticed that you added or changed content in an article, Homeostasis, 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. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Thanks, Ainlina(box)? 17:20, 2 January 2021 (UTC)

Hello, I'm Y.ssk. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to University of California, Berkeley—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. Y.ssk 18:57, 31 August 2021 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did with this edit to Zhao Wei. Your edits appear to be vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you. Materialscientist (talk) 19:15, 31 August 2021 (UTC)
