We have created one event for group registration and when someone register under multiple/group registrations, each person gets an email so is it possible to stop sending email to each of them ? We need to send email to only person who pays bill.
Also is it possible that first registrants email can be required and the additional registrant email addresses are optional.
We try to find such option in configuration of DTRegister but we did not get any option.
There is a setting in the General tab of Configuration for whether or not to send that email to all group members. You can disable that, then it will only go to the billing contact.
All group members will have the same fields display and be required. You can differentiate between members and billing contact, but not between each member.
