Every user has a subscription to a personal channel. A user can subscribe to additional channels, if the user has the privileges to access additional channels. A user cannot unsubscribe from a personal channel, but a user can delete job notices from his personal channel. An administrator sets options on Users—Properties—Jobs to control whether iHub sends job completion notices to a user’s personal channel by default, and if so, under what conditions iHub deletes notices. The user can also set these options, on Personal Settings—Jobs. A user scheduling a job can also control whether iHub sends a job completion notice for that job. If the user decides to send a notice, it appears in the user’s personal channel and any other channels the user specifies when setting up the job.
