Gravity Perks Disable Entry Creation Addon GPL Overview:
Gravity Forms must create an entry in order to function properly. Rather than truly disabling entry creation, Gravity Forms Disable Entry Creation will automatically delete the entry and any associated files after the submission process has been completed.
Additionally, if the form has a User Registration feed, the entry will be deleted once the user has been activated, created, or updated (depending on how your User Registration feed is configured).
