A category doesn't need to be created to be used on an article (though this is poor maintenance and creates a blue redlink). A category is actually created when you create the category page in the category namespace. After you type in a name as described above, click on the link and then click create. Add a description of the category and publish. Also consider organizing your categories by putting them in related categories. Doing so is a benefit to the wiki and its readers.
