Notification settings are global, except Tour Notifications (see Configuring Tour Notifications), so when a Notification type is set to ON you will receive Notifications from all sites for which your account has permission to administer that area. If your account does not have permission to that area of a site, you will not receive Notifications, even if the settings are set to ON.
For details of setting account permissions see 'Creating Accounts'.
To view triggered Notifications see 'Viewing Notifications'
