Howto enable recaptcha

First install the Ambetia’s great plugin:

http://github.com/ambethia/recaptcha/tree/master

Follow the instructions on its readme. Basically you’ve to set the env “RECAPTCHA_PUBLIC_KEY” and “RECAPTCHA_PRIVATE_KEY” variables. Then just set “plugins.tog_user.captcha_enabled” setting to true.

This will automagically enable the recaptcha banner on user creation and validate it on the server side on submit.
