Hello festival. Barbeque Festival received a quite complex theme to show off. The theme was built in wordpress. Contains registration forms for judges, contests and classes too. We used PHP, MySql, jQuery, ajax-submitions and fine tuned css. The theme is fully responsive.
Every registration is saved into the database, and after every registration we are notifying the client of the new registration. The client, using the dashboard can easily view, approve, reject or even delete new registrations.
The theme is highly customizable.
