Good for his parents. In any case, if he's got Poser 5 or Poser 6, there's no need for conversion because Curious Labs now supports common data formats on both platforms. If he has to deal with older PC-specific formats, fmorgan has a couple of free cleanup utilities that don't require running MacConverter in Classic mode. If he's stuck with an ancient Mac and Poser 4, of course that is sad; almost as bad as being chained to Windows. ;-)
