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.
