This is exactly what I needed. Very functional, easy to use.
Create great and functional forms with Formidable. You can create forms and the mails that are submitted. So no more hardcoded templates, only easy WYSIWYG mail creation. All submissions will be logged and saved in C5 Dashboard.
Formidable (Lite Version)
Formidable Lite is a minified version of Formidable (available for c5.6). It does the same, but some elements are not available and some functions aren't there.
If you are looking to create a simple form, this is it!
