We
gather traffic patterns and site usage information to help
us develop the design and layout of the site and to learn
about what parts of the site are visited the most. As a standard
practice, your random study code number is used to confidentially
track content preferences and traffic patterns. Your name
and any other identifying information will not be matched
to this study code number based on usage of this site. Therefore,
no one will know (by name or any other identifying information)
anything about your useage of this site, including your comments
at the end. This random number lets us keep track -- on an
aggregate basis (that is, summary, not individual) -- of how
many times individuals are doing specific things, such as
visiting our site each week, without specifically knowing
who those individuals are.
