The recaptcha option doesn't work.
After selecting 'Use recaptcha' and updating the settings I get the error "You need to supply reCAPTCHA API keys if you want to use reCAPTCHA. Please enter private and public key values." but there is nowhere on the page to enter the keys.
I still get the same error even after I manually enter the keys on the edit page.
This problem happens in FF & IE.
