After talking with the folks at Xsanity I have decided to try and open up comments to the site. You can still auth and post comments if you have an OpenID account, but you can now do so through the standard WordPress method provided you fill in the Captcha info. We’ll see how this works. Last time I tried comments there was simply too much spam. I’m willing to give it a second shot though, especially with the fancy-schmancy OCR whatnot enabled…
To get Captcha to work I used the WP-reCAPTCHA plug-in available here. In order to activate it you need an API key from recaptcha but once you paste that into the fields you simply enable the plug-in and then re-enable comments on the WordPress Settings page. All in all, took less time than writing this post.
