chose your formatting and duplicates are identified.

I'm looking at the class rosters for all 6 of my classes this semester at
UCF. I want to put all of the names in an excel spreadsheet and then find but
NOT remove any duplicated names so I can contact classmates that have more
than one class in common with me and work together with them. What's the
easiest way to do this?
