I have used the Captcha, and Liked the puzzle. You guys really are amazing. I like the way you noticed that the captcha had mul-functioned and you sent a mail directly with pages where the issue was, I was almost loosing hope but within a day the issue was sorted and now am getting new registrations on the site.
Keycaptcha is a very useful and great tool, it works perfectly with Joomla. Many thanks to support-team of Keycaptcha who respond really promptly.
Thank you for your review
