In the Requester Details section of a request, over to the right and just above the Subject field:

I have been using this field to include others so that they get updates on the work order.  Thinking they would get the same emails as the requester.

But that is not what is happening.

Can you please direct me to where I should go to see how this works, or perhaps you know, or perhaps it needs configured?

Or... maybe it does something other than what I am thinking it would do.
