Project Task Resource assignment notification is a trigger that is going to be very useful and helpful to many organizations.
The scenario would be
1. A new or existing task is assigned to a resource
2. An email notification is sent to the resources with details like Project Name, Task name, Task ID, Start Date, Expected length of the task, end date
This trigger should fire if the task is reassigned and/or if any modifications are made to the task after it has been assigned.
