I recently changed my email on my Seti@Home user account
at the website. I am using the command line client version under
WIN XP and I am unsure how to change the email address for
the client side software.  Normally there is a prompt to enter
the email when the client is first installed on a machine. I am
unsure how to change the clients email information if it is
already installed.
