We need a simple visual verification password, something like Captcha, installed on our Virtual Greeting Card Server Script to stop automated robot spammers. This is an open source CGI script from Big Nose Bird that is used with simple HTML Ecard forms, and it can be changed or customized in any way we'd like. There is something available called Protecting your form input using MD5 and Perl. Not sure if this would work or not for this particular script or not. This script has been customized to our specifications.
