What is a subscription

In the Jabber World, being able to see somebody else's presence on the net is called being subscribed to that person's presence information.

Subscription states

There are four primary subscription states, named depending on the subscription direction between a user (you) and a contact (a remote user).

• None -- the user does not have a subscription to the contact's presence information, and the contact does not have a subscription to the user's presence information
• To -- the user has a subscription to the contact's presence information, but the contact does not have a subscription to the user's presence information
• From -- the contact has a subscription to the user's presence information, but the user does not have a subscription to the contact's presence information
• Both -- both the user and the contact have subscriptions to each other's presence information (i.e., the union of 'from' and 'to')

Authorization Actions

There are three authorization actions that may be taken between a user (you) and a contact (a remote user).

• Resend authorization to -- the contact is given authorization to the user's (your) presence information
• Request authorization from -- a request is sent to the contact for the user (you) to receive authorization to the contact's presence information
• Remove authorization from -- the contact's authorization to the user's (your) presence information is removed
