The only Overdue Ticket notice built into osTicket is for staff.
I was afraid that that would be the answer :)
I would think, though, that if you wanted. You could edit the file that generates the email to add a recipient for the user. I have not messed the email settings, but the premise make sense to me.
I agree, however, I try to avoid doing that as it will require me to remember to make the change when a new version is released.... and relying on my memory is dangerous territory ;)
Thank you for the reply
