In a self-registration team, team captains are only responsible for creating teams and pay for their own entry fee. To achieve the request for A) team captains to pay for the whole team and B) team members to register without making payments, we can set up self-registration team categories with these two steps:
Create two separate price types of team captain and members
Set a price per team for team captain's registration category, and $0 for team member's
Note: This setup requires a known maximum team size
Detailed steps are listed below. We used an example below to demonstrate the setup process in steps and screenshots.
For example, registration category "10KM Running Category - Team Entry" allows self-registration teams. Maximum team size is 5 persons. Its price is $20 per person. Hence, entry fee of a 5 person team is $100.
