Enterprise Solution (ES2) livecycle by Adobe

I attended the above and found it slightly friendlier and ease of use when creating workflows. It has the capability to extend the pdf to allow users with the reader to digitally sign their contents. i have a question for them as how do i save the signed copy once the users fills in the contents. There were some bugs found when using the Workbench based on eclipse development. More to come when i attend the second day.
