An active contact belongs to one or more contact lists, and there are two ways to manage subscriptions of contact lists. To manage a particular contact's subscriptions, you have to modify the contact information directly. Each contact's information contains a list of contact lists to which the contact has subscribed, and by modifying this list, you can manage the contact's list subscriptions.
