I created a form in forms central by modifying a template. Can you save it as a PDF document or do you have to use it online?
We just added the ability to distribute your form as a fillable PDF form and have all of the data submitted back to FormsCentral. I wrote up a forum post that explains it in more detail: http://forums.adobe.com/thread/994199
Give it a try and please send us your feedback on it.
