I have one staff members who wants all the appointments entered on our public
office calender to "show up" on his individual calender. Is there a way to
have this occur automatically?

I'm familiar with copying appointments out of a list view of the public
calendar and dropping them into the individual calendar. The problem with
this approach seems to be the creation of duplicate appointments if you don't
clear the individual calendar first, which can get tricky if you are trying
to preserve the indivdual calendar appointments.
