Having dealt with Lulu on a couple of exchanges on JobOptions, I have to see there is a need for better information about how JobOptions interacts with Adobe.
The page on how to create a PDF says flatly that JobOptions will load into all Adobe products. That's clearly not true as you quickly learn in trying to load it. The page should say you have to have Adobe Acrobat Pro, according to Tech support. That's mentioned only in a link that's not one you would look for right away. Then having seen the video on how the system works, I have to wonder if Lulu supports Acrobat Pro X since the way the screens are set up in the demo don't match what I see on my screen. I'm still waiting for an answer for how the whole thing is supposed to interface because something is missing in the explanation.
