A simple, yet effective, Joomla! captcha plugin that uses a question and answer method.
What is the 4th letter of the word 'foxtail'? ... possible answers: t
How many 3's are in the number: 1,347,237? ... possible answers: 2,two
What is the sum of 2 plus three? ... possible answers: 5,five
The plugin will also reject rapid submissions (bot?) of the form.
Captcha labeling and questions are customizable ... see file 'custom.ini.sample' in the language folder.
