Category Settings
Under the "Settings" heading in the admin left hand nav bar is the "Categories List", "Add Category" and
"Edit Category" links to administer your site's categories. All of these links are for administering your categories.
Categories List simply lists your current categories, and you can also edit or delete existing categories from that page.
Add Category give you a blank record to create a new category, and Edit Category does as the name suggests. Through the Edit Category link, you can select a specific category you wish to edit.
You only need to create two levels of categories. The root level and child. When you wish to create a new category, you must choose the parent (root) category or select from the dropdown list of categories which parent category you wish the new category to be the child of.
Article Blaster Pro comes with pre-created categories, but you may change the names, add, edit or delete categories as you wish.
