     Please, please, please read the material at the torproject.org web site.
Then read the documentation.  The developers have put a lot of time and effort
into writing good documentation for us to read and understand.  An awful lot
of the questions you have been flooding our in boxes with, including the
questions in your message above, could have been avoided by your taking *your*
responsibility to read the documentation that has been provided to you.  Note
further that the bulk of the documentation was installed onto your own
computer as part of the tor installation.  Please read it.
     Once you have done your homework, people on this list will be much
happier to address any questions you still have after you do your part.
