I need to enable commenting and mark-up in Reader 8.0. I need to be able to use the More Tools drop-down menu. I use Jaws To PDF softrware for writing PDF's. Autodesk's Design Review is not ready for prime time and from what I see that is available with "Commenting and Mark-up" it's what would work for us here, but I can't figure out how to enable the functions. WHAT DO I NEED TO DO THIS?
