Guests
Go to Components->BlooKing->Guests.
In BlooKing each booking is associated to a guest. At
least the full name and the email have to be set. For your
convenience you can create a guest from an already existing user of
your site. When
receiving bookings from the front-end if a user is logged in the
guest will be automatically associated with the member of your site.
In addition the next time the same guest returns for another booking
the entered details will be remembered and the final form will be
auto-completed. If the guest details are changed the guest record
will be updated.
