[otrs] Send mail to queue owners when ticket is modified

Hi, we need everybody watching a queue to be notified via mail if an agent has updated a ticket. Because all agents shall see what has been done on a ticket in case we get asked by out users. Is there a way to accompish this, or can it be hacked in ? I didnt see that its not possible when I implemented otrs for testing, unfort otrs might not make it if this cant be done because if an agent works on a ticket and then closes it, the other will never know unless the lookinto all the tickets before being closed.... thx for any help here.
