Unless there's an order that wants to be retained.  But I would change
the list into a list of user objects, rather than of strings.  And I'd
know that eventually it would be a sparse list (as users come and go,
and you don't want to reuse the indices).  So it would be another
dictionary mapping userid and User instance.
