Everyone I know uses PDFs but why aren’t people moving to DWF? I demonstrate DWF capabilities at almost every training event I do, but nine times out of ten when I return, the team are still using PDF.

If you want to get a grasp of the basics, this video runs through publishing, marking up, reviewing, re-issuing and even attaching other media formats such as PDF.
