 +==== Node Status Notification for Farber ====
  
 +An opt-in node status notification service is available for Farber users.  This service sends an email notification when any nodes in your workgroup transition between two of the following states:
 +
 +  * offline: down and not reachable.
 +  * online: up and reachable, but queues are disabled.
 +  * accepting-jobs: up, reachable and queues are enabled.
 +
 +The service currently checks nodes' statuses at the top of every hour and delivers email notifications at the bottom of the hour.  If you opt-in and any of your workgroup's nodes have changed state, you will receive ONE email message detailing the status changes.
 +
 +To opt-in the node status notification service for your workgroup(s), send an e-mail to consult@udel.edu with subject="Node notification opt-in Farber" and make the first line of the message body be
