I've created an interactive form and the users using Reader can email the XML data from it to me, and I can import that data into the forms using Acrobat Pro 7.0 just fine. The users have requested that they be able to save a copy of the *completed* form. We're also considering the upgrade to Acrobat 8 Pro and would "enabling Usage Rights" in the form through Acrobat 8 Pro enable the Reader users to save their completed forms or not?
