This configuration variable defines the users who will receive a list of expired content in addition to the authors of each content item. Notification queries define the criteria used to search for expired content.
If NotifyExtras is not set, the default value is sysadmin. If the NotifyExtras setting is in the config.cfg file but has no value defined, no extra notification is sent.
