Here's what they want:  About 35 people need to enter info into a
spreadsheet.  Each user needs to see only their own information.
Admin, though, wants to be able to see everyone's info.

Some possible solutions:
  (1)  Each user has their own workbook; they have a password that
allows only them to open it.  Admin has their own workbook, and each
individual user's workbook is linked back into Admin's so each user's
data shows up there.
  (2)  One workbook with one sheet per user and one for Admin.
Another sheet holds username and passwords.  On open, user is
presented with a form asking for username and password; only that
user's page will show, all others are VeryHidden.

Which way would work best?  Or is there a better way?
