User talk:CF21021

In your recent editing at Category:People from Crystal Lake, Illinois you added the name of a person, but that is not how categories work: they work by being linked from articles. It is best not to edit category pages until you have enough experience of how Wikipedia works to know how to use them.

You also removed links to several other categories. I don't know why you did that, but if it was a mistake you need to be careful to avoid making similar mistakes again, and if it wasn't a mistake then you should explain your reason in an edit summary. I shall restore those categories for now. JBW (talk) 23:42, 27 January 2021 (UTC)
