Safe Signup Form is a Wordpress Plugin that will forward a form submission to an email address, while preventing most automated attacks.

To do this it leverages Elliot Back's WP Hashcash -- an elegant anti-spam engine that uses javascript to determine if the form is submitted by a robot or a web browser.

An administration page provides three options for handling submissions identified as spam:

• Delete spam submissions.
• Flag spam submissions (and forward them anyway).
• Forward without flagging.

The basic plugin offers a simple name and email form, but the php can be easily modified to incorporate any number of fields.

Safe Signup Form is XHTML 1.0 compliant and has been tested in Wordpress 2.8.5, MSIE 7, Firefox 3, and Safari 3.
