Did you create the web form within FormsCentral? or is it just raw HTML?
I was just getting starting: I have a web form to either print, fill-out, scan and email back or create a PDF Form.
I ended up, as an expediency, printing, scanning, created a for using Adobe X, filled the form out, saved it as a PDF and emailed it back.
There has to be a way to tackle this task more efficiently.
