Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, discussion pages are meant to be a record of a discussion; deleting or editing legitimate comments is considered bad practice, even if you meant well. Even making spelling and grammatical corrections in others' comments is generally frowned upon, as it tends to irritate the users whose comments you are correcting. Take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. Apocheir (talk) 00:50, 3 May 2022 (UTC)

Please do not add original research or novel syntheses of published material to articles as you apparently did to Quadrilateral. Please cite a reliable source for all of your contributions. Thank you. MrOllie (talk) 22:22, 30 May 2022 (UTC)

Please do not remove content or templates from pages on Wikipedia, as you did to List of trigonometric identities, without giving a valid reason for the removal in the edit summary. Your content removal does not appear to be constructive and has been reverted. If you only meant to make a test edit, please use the sandbox for that. Thank you.
