Captcha

[#1]

I have been trying to get CAPTCHA to work in my online guest book page but the Madasafish help file says that it is already included by the use of the addgp.pl script automatically but I find that the Madasafish form html, on the using HTML forms page (example:- <form method="post" action="http://www.users.madasafish.com/cgi-bin/FormMail.pl" name="MyForm">) does not include the use of addgp.pl script and therefor CAPTCHA does not work on my forms. I really do need to get this facility to work due to the high instances of spam mainly from gmail accounts (bots). Please could someone let me know how to get and implement it within a form.
With best regards James

A simple fixed image and a single CAPTCHA code will defeat 99.9% of bots.

Thanks I will have another look around but I find some of them are not very clear as to how to inpliment it.
Cheers James

You might also want to take a look at Project Honeypot, not so much stopping spam there and then, but making them pay the price soon after
