[otrs] ticket owner problem

i have a little question When a ticket is created via customer webinterface it's owned by root and i can't delegate it to another user, i have to reply to the ticket first so it becomes mine. How do i set default ticket owner for a queue? When i created the que i selected i group and my agent user is in this same group but doesn't have initial rights to mess around with the ticket. greets, Wouter
