Hi, we want to deliver a revision 1.00 document to a customer, and allow them to make markups and comments to share with us, so that we might address them for a Revision 2.00. They are familiar with using Adobe Acrobat for making PDF comments, or using Microsoft Word review tab, but we're not a big fan of delivering Word files.

I understand that editing a document is not possible once it's signed. But is there a method for the customer to freely mark up the document or add comments/callouts? We do not want want to litter the whole document with input form textboxes - too much effort to set up for each document, and it doesn't meet the goal because this is too restrictive, when the comment might point to a particular word on a particular line, or a particular part of a graphic. What are the alternatives?
