I. About the Profile module
Participants can update their registration details directly from the app, ensuring that their information is always up-to-date for the event.
II. Configuring the Profile module
You can enable the Profile module in the Event app module. In the module's settings, add the fields which you would like your participants to be able to update.
You can create new fields using the Global fields manager, or its Event level version.
III. Using the Profile module as a participant
Participants then get to access these fields and they can update them at any time. They get a notification that the changes have been successfully saved.
