I would like my clients to able to feedback a ticket based on rating
that they would just select when a ticket is resolve. With this I would
be able to measure the feedback to my clients based on this. I don’t
know if this is already in place on RT but it would be nice to know if
someone could point to right direction.
I think to do this you would either need an HTML template that send out as an email asking the client what they thought of the help they received. Or create a custom page that asked for the rating and then updated the corresponding ticket.
