Thank you for the response. The problem is that there is a relatively
small number of people I'd like to exclude, and a much larger number of
people that I'd like to provide read priveledges to. Is there an
alternative to giving a large number of people read permissions without
using the default then? Alternatively, is there a way to restrict an
individual user's persmissions if they have greater permissions through
another group level permission setting (e.g. the default setting).

Thank you.
