I would like to send notification emails to everyone in the administrator group when certain things occur within SilverStripe (i.e. publishing pages, file uploads, etc.). I tried implementing a workflow module and setting up notifications that way, but it was overkill. I found the "Notifications" and "Email" classes. Should I extend the DataObjectDecorator and SiteTreeDecorator and use one of those classes to manually send emails to the Administrator group? Isn't there an easier way?
