Por favor…
What is it you’re after?
I’d love to have ReCaptcha built into FreeForm - maybe the ability to use EE’s captcha or ReCaptcha via a different set of tags.
You can use the Native EE Captcha for Freeform:
{if captcha}<p>Submit the word you see below:</p><p>{captcha}<br /><input type="text" name="captcha" value="" size="20" maxlength="20" style="width:140px;" /></p>{/if}
Yes I know that, but I have clients that get spam all the time with that captcha in place. ReCaptcha is new and I think (for now) a bit better at defending against spam.
I will add it as a feature request
