I realized that my previous post has been accidentally locked (password protected).
I am re-posting here. Tx.

Can somebody please tell me how to add Google captcha below the review?
I've downloaded and installed nocaptcha_v1.0.0. I've added the public and private keys and activated the plugin.
But I am missing something, since the captcha doesn't show up. I can't find any settings in the configuration section either.

Thank you!
