Enabling Commenting in PDFs for Adobe Reader using Acrobat Professional

We often send PDFs of typeset proofs to authors and editors for reviewing. However, we must remember that most people either do not have a PDF reader on their computers, or they have Adobe Reader, which does not allow commenting on PFDs unless commenting in enabled. To enable commenting in PDFs to allow authors to review them, we must first enable commenting using Acrobat Professional. This slide show demonstrated how this can be done.
