Setup your form status here: always active, active during a period of time, active only for you, inactive or active only on certain days of the week. This gives you quick control over the time span during which the form can be accessed by users. The feature is especially useful with registrations or contests, where you want to make sure that no overdue submissions are made.
In My Forms, you’ll notice a checkbox displayed on each form that states Active. Tick this option to setup your form’s status.
