Finally the premium wordpress forms plugin GravityForms has been released. Just watc
hing the demo on their site (at gravityforms.com of course) makes we want to purchase it. Though when looking at the comparison chart of the different licenses of the plugin available for purchase here it appears that even with the single site license you can use the plugin on multiple sites you just wont get automatic updates on all of them.
The prices are quite reasonable considering the apparent power and simplicity of this plugin making me recommend this plugin to anyone who uses WordPress as a CMS.
You can purchase this amazing plugin here.
