what is it?
Castle is a captcha type system for your website. It presents a question, and then evaluates the user's answer with the correct answer, to decided to allow them to do something. It is very simple to use. You simple include the file on the pages you would like, and then add two lines, one between some form tags <?php displayictc(mt_rand(0,3))?>, and the other in the processing section, compareictc('x','y').
The best thing? It can be expanded by you as much as you like.
Want to see it in action? Of course you do, testform.php has some example forms with the system setup. Try it out!
