Joost de Valk, over at Yoast, has written a great article on how to use Gravity Forms to submit custom post types using my Gravity Forms + Custom Post Type addon plugin. The tutorial also uses another great plugin called Types which I need to look into in a bit more detail. The articles walks you through a real world scenario of using the post type addon and is a must read for anyone that uses Gravity Forms.
Thanks for using the plugin Joost
