What is the "Custom User Identifier"?
You may have noticed a new "Custom User Identifier" field in all registrations and participants information sheet in the Organizer Dashboard. That's linked to a new API Endpoint used by organizers/developers that wish to follow their users/players across several tournaments.
If you do not use the API, you are not to concern yourself with this (participants can not see it), and if you do, you will find more information about this new feature in the API documentation.
