Hello, Jamal:  Thank you very much for making this article and other
preceeding articles available to me and others like me.  I have been
looking for this kind of clear and systematic evaluation on screen readers
for the past year.  I also like to thank you for other contributions in
the past which were unusally informative.  I, just like other visually
impaired users, will continually depend on you, and other knowledgable
educator like you, for your future assistance.
