For a commercial project based on Joomla i've the need to use a math capctha on various form, after testing and viewing the other captcha code i've decided to try this one, so i've asked some tech info to the developer, surprinsigly, in a couple of days i was able to work with this captcha on my project. So i strongly recommend this one for extensions developer that need to protect their form with captcha, consider that this is a plugin and not an hack, so you have nothing to do when you decide to upgrade joomla to newer version. Very good job man.

I've liked the honeypot project spam report on contact email. For fully usefullnes it can be better if a spam indicator is on subject too, in this way is more easy to configure an email client to filter spam mail. There are some other little things that need to be enhanced, but in my opinion this extenions is a good point of start

Simply works well. I hope that the developer continue the development, in my opinion maybe usefull on adminstrator side a toolbar menu item for copy faq item between category.
