When registering more than one person, you can enter the same email address for all members of your group. This will then populate all the fields on the personal information page with all the first person's information with the exception of the first and last name. Then you can just enter the next person's first and last name and click Continue. However, for each individual in the group you will need to enter the first person's email address, the first and last name of the additional group member, and select event(s) for that person. After each person's event(s) has been selected, either click Add Another Person at the bottom of the events page, or Continue if all your group members have been added.
