How does attendee registration affect existing Dryfta users with roles as speakers or reviewers?

If I launch registration through tickets and attendees use the registration form, will new participants be registered as attendees? What happens to users who already have Dryfta accounts as speakers or reviewers when they register as attendees?

When new participants complete the attendee registration form via Dryfta ticketing, they are registered as attendees, creating new attendee profiles. 

For users who already have Dryfta accounts with roles such as speakers or reviewers, registering through the attendee form does not overwrite their existing roles. Instead, it adds the attendee role to their profiles, allowing them to retain all original roles while also participating as attendees. 

These users can log in with their existing credentials to access functionalities for all their roles.
