[otrs] send email to person to whom ticket assigned?

Hey folks, I was just about to send out an email to my internal customers announcing our new system, when it struck me that it does not send an email to a person when a ticket gets assigned to them. I'd like that very much. Googling does not turn up much of anything for me. Can someone help? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"
