does anyone know if it is possible to share Mac InDesign files with a PC InDesign user (relatively smoothly)? i've created a flyer template in InDesign for a PC-using client, and we're trying to figure out the best way for him to change the particulars (events, dates, etc) on a quarterly basis and print it in-house. he considered getting InDesign for his PC, and having me send him my Mac InDesign file for him update every few months. i'm trying to find out whether this is a good option. any information will be appreciated! thank you.
