Reduce SPAM on forms?

Web robots are always looking for forms and submitting their SPAM to them. You can go a long ways towards thwarting these robots with the '{_SECURITY}' tag on your forms.

ProPageManager™ replaces this tag with what's known as a "CAPTCHA" system, which is a control on your form that looks like this:

 The idea is that the 'j69muv' is actually a graphic, and not straight text as is 'Enter the characters above'. If the user enters the characters correctly, they can submit the form. If the user gets it wrong, it presents them with a new graphic character string  and the user can try again.

Since spam robots generally can't read text embedded in graphics, they'll be unable to correctly enter the characters and submit the form.
