I have installed and activated this plugin - by following all of your instructions. However I have tested the actual contact form on my page, several times and it hasn't worked once.
I have checked the individual fields in the 'settings' menu and have also added [contact_form] to the body of the post/page in the editors HTML mode. However none of this is working because I am not getting any emails from the form.
Its a real shame that it doesn't work - as it means that I will have to find another plugin and start all over again!
