I am incredibly frustrated with this extension. After trying out many other form extensions (not many free one's to choose from), this one looked like a godsend. Unfortunately after spending an hour tinkering with Fabrik and searching for documentation, I see that they only way to get instructions is via paypal.
Hi sorry to hear you had difficulties grasping how Fabrik works, we have some help in the wiki for everyone to use. We also have a free getting started tutorial here:
If that helps perhaps you would consider re-reviewing (if that's such a word!)
