After you've created a new contact or opened an existing one, click the Categories button at the bottom of the Contact window's General tab.
A list of available categories appears; click the check box next to the category you want to assign to select it.
The category is listed on the General tab; click the Save and Close button.
To organize your contacts, you can assign a category, such as Personal, Business, and so on, to each contact. You can then sort your contacts by category (see the task "Changing the Contacts View" later in this chapter to learn how).
Assigning Multiple Categories
You can assign more than one category to a single contact. To do so, simply click any of the applicable category check boxes to select them.
