The users on the forum have the ability to subscribe to topics & forums. By subscribing to a topic a user will receive an E-mail or ICQ notification about any new posts made inside that topic. The subscription to a forum on the other hand will notify the user of any new topics created in the forum.

To prevent sending multiple notifications the notification system will only notify the user if they have no unread notifications for that particular forum or topic. This is extremely useful for active forums where many messages can be posted in a short period of time causing a massive amount of notifications to be sent to the user about the same content.

Each forum member has access to a personal subscription control panel, which can be used to see what subscriptions they currently have and allow the user to unsubscribe from any of the subscribed to content.

If specified by the administrator, the forum can include the full body of the message in the E-mail notification, so that a user can read and reply to the message directly via their mail client. These notifications come specially formated, so that they are properly displayed on all e-mail clients, regardless of whether those mail clients support HTML or not.
