I have Adobe Acrobat 9 Pro and can add comments to a pdf. The pdf file properties shows no restrictions and commenting is allowed. But there is no option on any toolbar to "enable commenting for free acrobat reader". As soon as I send the pdf via email or save it on a disk and open it in another computer with just Adobe Reader, comments are disabled and there are restrictions attached to the pdf all of the sudden. I have been all over the Adobe site documents and forums and no where is this addressed. It seems like such a simple task. Why does my version of Adobe Acrobat 9 Pro not have the "Enable comments" feature under any of the tools on the toolbar? How can I send a pdf with user rights?
