In the effort to combat spam in the online forms - we have added the ability to add a Q&A process to check if the submitter is human.
Add in the hidden field icwsAnswer, this is the "value" or answer of the question you'll be asking.
<input type="hidden" name="icwsAnswer" value="15" />
Then add the question field icwsQuestion to your form. This can be anything such as "What is 6+9" or "What color is ", just make sure that you make it clear and easy for a human to get the right answer.
This simple process will look at the question and answer and if there is not a match - tag the submission as spam.
Check the documentation for more information.
