I'm a web developer and frequently need to set up contact forms on websites. Many of my clients detest regular captchas, and against my advice, would ask to "just leave that off" their web forms.
This extension solves that issue. With its 'choose a picture' and/or 'secret word' captcha system, eyeballs can now be saved. And my clients don't have to choose between spam or inflicting pain on customers.
Thanks for this!
