Great, thanks Andy!
I think having a simple question (<input name="Question" value="" size="40">) after the CAPTCHA information, will deter the remaining manual SPAMMERs and help keep this beneficial add feature available to the visitors. Since the answer (using text or numbers) will be in the code within the add.cgi, they will not be able to pass this security feature.
Ideally, I'd like to be able to use a %Question% in the add.html template to pull the Question and Answer box into the add.cgi, similarly to the way the Human CAPTCHA system works. Thus, future changes to the two "Question and Answer" variables can be easily done within add.cgi and reuploaded as often as needed.
Thanks again. I look forward to hearing from you soon.
