Install this free Captcha script onto any page that requires your site visitors to submit any form. The script will freeze your form submit button. Your site visitors will need to answer a simple arithmetic question where the answer would only be a 2 digit anwer. The answer will need to be checked and if correct, the Submit button is then released for the visitor to submit the form. If the answer is incorrect, the question is reset hence the visitor is required to answer again. This arithmetic question is more secure then the usual captcha script as not only is the fact that the numbers in the question not easily detected by bots, but only humans are able to answer the question correctly. the Operator cound either be plus or minus. The question is easy to answer by humans as the second number will not exceed the value of 10. Easy to install as there are only 4 simple steps to follow. Instructions are in the README file.
