Codecanyon Mega Contact CodeCanyon

Mega Contact is a versatile and flexible Ajax contact form builder created from the ground up. It allows you to quickly construct an Ajax contact form and incorporate it into your page. Both, front (JQuery) and back-end (PHP) are written in an Object Oriented style that allows for extensibility and code reuse in an efficient manner.
With the exception of the reCaptcha service by Google, Mega Contact does not use any third party code or plugin. There is a single JQuery file written as a plugin and a single PHP class file to handle all the back-end tasks.
