Description: This modification allows you to create an infinite amount of sub categories in your forum. Each sub category can also have an infinite amount of sub categories. To modify the sub categories, enter your CP and go to Primary Settings->Forum Settings, then click on the "Add/Review SubCategories" link. To delete a sub category, simply give it no name, and click the submit button. You can add forums to sub categories just as you would add them to normal categories.
