I think it will be really useful in Remedyforce to have the possibility to "subscribe" or "follow" a ticket so that the system may send a warning to a list of predefined "stakeholders", whenever there is a change in the contents (Status, Notes, etc.) of a Ticket.
I've seen that capability in other systems under the term "watch list".
The members of that predefined list of interested people may or may not be part of the Queue to wich a Tickete is assigned.
I think this is specially useful for support organizations in which the work done by some staff has to be supervised by some managers, or simply to help in the trouble-shooting of a given critical incident.
