Yes. Another school’s coach or adult may pick up your registration packet, as long as they are also listed as an attendee for your school in Tabroom.com. Being listed as an attendee indicates that your school administration is aware that this individual is attending the tournament with your school.
If someone from another school picks up your materials, they assume responsibility for receiving and safeguarding your school’s credentials until they are transferred to you. Your school remains responsible for ensuring all participants receive and maintain their credentials.
