Organizing Articles in Article Manager

If you will have a large number of articles on your site, a second reason to use categories is to simply group the articles so you can find them. For example, in the Article Manager, you can filter articles based on Category. So if you have 200 articles in your site, you can find an Article more easily if you know its Category.
