This Customer Data module is a continuation of my original Maths Captcha Hook.

Remaking the original hook into a CD module means that you can more easily protect other pages in your site, and more easily style the Captcha in the chosen pages.

As it is a now a module, there are no core code changes which means this Captcha is super simple to install; Upload. Turn On. Your site is protected.

If the price of this addon does not suit your business, contact me anyway. I'm sure we can come up with a good deal that suits each other. Prices are not set in stone.
