We have been INCREDIBLY happy with Formidable - not just in the level of service and attention through this support forum, but in the amazing capabilities it's offered us. It is the best plugin we've ever seen and it's absolutely revolutionized what we are able to do with WordPress.
This is by far one of the best plug-ins I've come across in a long time, if ever! It is truly a fine plugin with so many possibilities. I'm glad to know I bought the right one for a change!
