Good one
By , for WP 3.8.1

I'd pose a 5 start obviously, but in some cases it misses some spammer account - but that's silly - it's actually a doing a nice work in both registration and login. Excellent one. Would like to recommend for any site. :)

works well, though fixed color choices may affect color-blind users
By , for WP 3.4.2

I'd like to see more color variation in the output to assist those who are red-color-blind (among others) in seeing a captcha after refreshing a possibly bad one they cannot see clearly.

Also Mike, you might consider incorporating reCaptcha, since both other plugins here on WP site seem to have ceased development.

I've used your si-contact-form plugin before and it was nice to find this as well, when I needed it. most of the other captcha choices were abysmal. :D

Great plugin
By , for WP 3.4.2

I have been really happy with this plugin. Recently however some spam has been leaking through. Not entirely sure if these are being placed by humans or automated, so it would be unfair to blame the plugin at this point. Will keep an eye on it...
