Email when notes/updates are added to shared tasks

I have a variety of shared tasks with members of my team. Having it email everyone on the team when those tasks are updated would make interacting a lot easier, as it would make it clear when action has been taken on the task.
Having it email when anything happens to a shared task would be really really good.
