Thanks to Jesse Heap for making a plug in for PHPLIST. I found some code from GNU , and was able to modify the plug in to accept the Captcha in the form. This is a mod to Jesse’s PHPList Form Integration.
Background:
PhpLIST is a open source ListServ program that runs on PHP Web platform. I found CaptchaCode mod by Alan Fairhall. However, I needed the Captcha for the Plug in Widget used on WordPress by Jesse Heap. So, using the CaptchaCode PHP, we are able to accomplish adding Captcha to the Widget. Here’s how.
