Let users submit appointments from frontend. You can view & manage them in backend.
The Booking Plugin is a simple but nice, clean frontend form. Users can submit appointments. The entries are managable in the backend. Perfect for any kind of appointment requests. E.g. if you are a Hairdresser your customers can submit their wished dates. If you are a musician, this is perfect to do your bookings. You can manage them in the Backend and view all bookings in a sortable, clean table. You can set the Appointment to "done", rate it, count how many times you've met that user, how many bookings were successful and many, many more.
