Our Take on Tools.

It should come as no surprise that our site is based on Joomla as we develop tools for the Joomla Extension Directory.

Captcha and Recaptcha

Joomla 2.5 includes ReCaptcha as standard and all one has to do is enable it and it is present in the basic registration process.  There are other plugins etc. and many components also offer different in-build captcha options.  However do you really want more than one type of captcha solution on a site.  We decided upon a single solution and following the Joomla core implement ReCaptcha in our components.  One it is easy to implement and two it makes it easy for our component users, and site users to offer consistency throughout.
