This form component is good for beginners, but also for more advanced users. You can create very complex forms with it, but also some easy forms if you want. Everything is possible.
Some other nice features are the auto update checking. Everytime you go to the component via Joomla it checks if you have the latest version installed and let you know.
Another nice feature is the anti-spam of this form component. It has a LOT of cool and new anti-spam techniques build in. There are no captcha's (so no hassle for your customers). The spam controls are invisible, but they work perfectly! And if you want you can also use 3th party spam controls, like Akismet and Mollom (which are great too).
This one is the best, for sure!
That's also why a plugin is better then a module: this is always good, but for a module you need a good positioning.
The support is good too. Google didn't recognized my website so I emailed Kenneth. He helped me and at last it seems that it took google 2 days to recognize I had installed the code on my website. It wasn't this plugin.
Kenneth, thanks for this one!
