[rt-users] Grant resolve right to requestors

[L B]

Hi,

 Is it possible to grant the resolve right (only) to requestors ? I
want to allow self service users to create tickets, reply to tickets,
and resolve them.

 I'm afraid I need ModifyTicket right, and I don't want to allow
requestors to change rights to something else (especially deleted).

Thanks,
