Perfect for campaigns, registrations, contests, or any time-limited or capacity-restricted service. The plugin automatically manages capacity, prevents over-registration, and gives users clear feedback about the form's status. Administrators can track form status through colour-coded preview indicators and receive one email notification per event, not one per visitor.

The plugin integrates seamlessly with RSForm! Pro's existing features, including conditional fields, multilingual support, and all validation rules. Every deadline is a single moment in time: the form closes for all visitors at the same instant, with daylight saving transitions handled automatically.

For operators, the plugin offers robust administration tools: three timezone modes (server, visitor's local time, fixed), real-time countdown timers, email alerts on expiry or when the capacity limit is reached, and dynamic closure from your own PHP code. The frontend experience is simple and clear: the form closes in place the moment it expires, without a page reload and without losing anything the visitor has typed. An automatic "closes in 2 days" warning appears before the deadline, and popup notifications show the form's status. Late, full or closed forms are always rejected on the server, even with JavaScript switched off.
