The Will Attend/ Will Not Attend field of your form allows:
Your guests to decline the invitation to the event.
The count of your confirmed participants and thus of your credits
Sending automatic confirmation/decline emails
This field is not deletable on the registration form. It can be hidden by clicking on the “Advanced parameters” of the field and selecting the “Do not display the question” option.
Be careful, this action is not recommended in case of non mandatory events:
Each guest who will fill in the form will be considered as confirmed, and will receive the automatic confirmation email and will cost you 1 credit.
If the guest is not able to attend the event anymore, the organizer will not be informed.
