We had great response from Joomla community over our First Generation
of Captcha System. The basic problem with last version were dependency
on Template Overrides and Compatibility with different versions
of Joomla Component.
We took problems in first generation system as a challenge to us, and
now we are presenting a Next-Generation Robust Captcha System i.e.
JoomlaXi Joomla Captcha (codename is XIJC). XIJC not only resolves the
problem of previous versions, but also enable an administrator to use
captcha, virtually on any page in Joomla. This way you can secure your
non-standard pages, without digging into the code.
