This plugin adds Googles reCaptcha support to JForm compatible with Joomla 1.6 and 1.7, most importantly the user registration form. All you need to get a reCaptcha is a public/private key pair from google.
In order to translate this extension into your native language if not supported you can perform the following steps.
Change to plugins/system/rvs_recaptcha/language folder
Copy en-GB folder to xx-XX (your language code)
Rename the files inside the new folder
Change the language strings
If you translate this extension into another language I would love to add the translations to the plugin package, so if that is a possibility please contact me.
