Thanks Graham,

If I read this correctly, it loops through each user on the system, finds
the user in question, and checks the default group.
The problem is a) there are 1500 users, and the "staff" & "student" groups
are not the default one.

does user[3] return all the groups the user is a member of?

Though I could use the same structure to loop through the members of the
staff group (about a 100) and compare that way.

Still thinking it through.
