## Description

Hercules Recaptcha uses the latest Google Recaptcha API to more accurately determine
if users are bots or not.
 If the user is not logged in it will display a Recaptcha
for the user to fill out in the comment form. If the user disables javascript and
is not logged in then comments will fail to submit.

The Recaptcha is also added to the registration page for both multisite setups and
single blogs. There are options for
 having it show up on comments and/or the registration
page, as well as options for its position on the comment form, and which style (
Google gives only two options, dark or light).

## Screenshots

 * This is how the Recaptcha looks in a form on a real Wordpress theme.

## Installation

Add this plugin by uploading the zip using the “Add Plugin” feature built into WordPress.
Otherwise manaully unzip the folder
 and upload the entire directory to your blog’s
plugins folder ( /wp-content/plugins/ ). Next you have to activate the plugin.

Lastly, to make it work you need to go to the Hercules Recaptcha settings page (
a submenu of “Settings”) and add your
 site key and and secret key. If you don’t
have these yet you need to go to https://www.google.com/recaptcha/ to register your
site and get keys.

## FAQ

  Why isn’t my Recaptcha rendering?

First of all make sure you are not logged into WordPress and that you are viewing
a post that has comments enabled.
 If the Recaptcha isn’t displaying then you may
have not set your Recaptcha keys yet. If it is displaying an error message then 
you are using invalid keys (ones not associated with the domain that your blog is
on) or there is some sort of error in the keys (like an extra space in them).

  Where do I get Recaptcha keys?

If you don’t have these yet you need to go to https://www.google.com/recaptcha/ 
to register your site
 and get keys.
