    It's time to stop annoying users with unreadable text or silly questions. Swipe and welcome is all we need, and this is just perfect!

    Works great so far, I highly recommend it for an easy to use and un-intrusive captcha option. Works great on desktop as well as on mobile devices. Keep up the good work.

    Really nice and slick captcha method. Easy for humans - way easier than recaptcha which I find infuriatingly hard to get right sometimes.
    So it's installed on AVForums.com and working nicely.

    This is a really amazing captcha add-on. So far I've not had any bot registrations and is very easy to verify. I really hope this keeps being updated and remains effective. :)

    Terrific add-on and captcha. Users love it.
    Just be careful of the timeout option, if you set a low value than no-one can ever pass the captcha and instead get an error. Put my as 0 (disabled) and its great.
