First the good things.
Easy install, easy setup.
After creating a form just link it.
The best part is setting up the fields. Does not get any simpler.(i really dont understand who came up with the "form designer" idea which in other extensions, That is scary)
This is where the good part stops.
The select field is buggy. I added a field and then deleted it. After that it refuses to add anything. I just skipped a select field in the end.
The first time I installed it, it refused to send an email, but strangely started working after a few tries.
But still does not send email to cc(in email settings).
The form displayed properly on one site but the inputbox was giving a 100% width(which I corrected css)
On the second site. The input box was giving a proper width(that is the default) but the Tip icon was overlapping it.
I just could not figure out why. So this is where I am going to stop using CK forms.
I am also going to remove it from the other site I have installed. Just cannot trust this one.
I am sure if the bugs are cleared out and you can easly add select box or a select pull down menu.(with javascript validation and reCAPTCHA support).
Add the ability to copy paste html code(design the form in dreamweaver and paste the code) and this could be the "chosen" extension for joomla.
no support site/forum.

I got this working in matter of minutes on a Joomla 1.0.x site.
This is great plugin very nifty. Looking forward to a 1.5 native version of this plugin.

Thanks a lot m8 for this.
