Hi, I am experienced and certified Programmer. I know Classic ASP and various other programming languages. Since producing images with Classic ASP requires paid/expensive third party components, I will be using Mathematical Captcha to prevent Spam. Mathematical Captcha is a simple math problem such as "How much is Two + 8" and "How much is 2+9". Bots are usually built to resolve Image Captcha and they fail to pass mathematical Captcha. It can effectively stop 99% of the spam. Thanks, Amanat Ali
