Hi Giovanni. Comments in Word and Pages are interchangeable. I've dealt with editor comments sent back to me in a Pages file directly in Word. They actually look a lot better there than they do in Word.

Not only that but changes pass over too. So if you have track changes on in Pages when you export to Word those edit changes are there just as if you'd made them in Word (I assume it works the other way too but since I don't originate things in Word I can't check easily).

Glad you find my ramblings interesting.
