Notify a user when you assign them a task

One of the main principles of our simple CRM is to show features only when they are relevant. If you assign a task to a different user, the notify check box becomes available.

This feature design is it to notify the user via email if another user assigns them a task. Presumably, the other user may or may not be logged in to address two, but has access to email, and needs to be notified of a task before the next day when they will be emailed a task list from address two.
