WCP Contact Form

I'm writing a book about WordPress for the non-techie, and this is the best contact form I've found with an easy configuration screen and a full set of features. The default settings are also right, except that you'll want to use the little gear on the Captcha field to change it to use reCAPTCHA, once you've entered your keys.



Best for ease of use

Cool !

The contact form plugin with dynamic fields, reCAPTCHA and other features that makes it easy to add custom contact form on your site in a few clicks
