Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia.

Please refrain from making unconstructive edits to Wikipedia, as you did at Animal echolocation. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. DoebLoggs (talk) 11:01, 18 October 2022 (UTC)

Please stop your disruptive editing. If you continue to add unsourced or poorly sourced content, as you did at Human echolocation, you may be blocked from editing. Tacyarg (talk) 12:04, 18 October 2022 (UTC)

Hello, I'm Materialscientist. I noticed that you made a change to an article, Manaki brothers, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 09:06, 22 January 2023 (UTC)
