Subscription notifier is a special notifier with the name "subscription_notifier". It is used by QuickBuild to send notifications to build subscribers (can be managed through My settings menu for each user). For each supported notify method (Email, MSN messenger, etc.), you need to define a notifier of that kind with the name "subscription_notifier" in the root configuration. For example, if you have two notifiers with the name "subscription_notifier" defined in root configuration, and one is of type "Email", and another is of type "Jabber", the notify by drop down box (refer to section manage subscriptions) only contain two methods, Email and Jabber.

Just like other notifiers, subscription notifier can be overriden in child configurations. Build notifications of particular configuration will be sent to its subscribers using the subscription notifier defined in the nearest ancestor configuration.

Also the manual build notification (that is, users can choose to be notified of the newly generated build when they triggers a configuration manually) works the same way as build subscription and makes use of the subscription notifier. The only difference is that the manual build notification is a one-time subscription and is only valid for current triggering of the configuration.
