There is a setting under the Tech Group that sets the default check boxes for client, tech, level tech and group manager. Under Setup go to Tech Groups, then select Tech Group Levels. Click on the Level you want to change (we only use Level 1). Under the section Default Selected E-Mail Recipients, check the boxes that you want to have checked when the ticket is created. Note that the defaults are not set on a ticket until this Tech Group is selected on the ticket.
