This is a fantastic plugin.
I was looking for a form management plugin and as many have came across Gravity Forms first. After having played with GravityForms for a bit I was surprised when I found out that it did not allow for the front-end editing of submissions.
I looked at a range of alternatives on code canyon.com but eventually settled on FormidablePro.
FormidablePro offers front-end editing, it works with custom post types and the support is fantastic. I am completely amazed at how the small team at Formidable Pro spend so much time assisting their users, even looking at the code and helping to identify errors.
Anyway, great plugin and amazing service.
