I don't know what you're talking about.  Who is "cypherpunks," and who are
you?  Please don't answer...I'm just trying to figure out how I started
getting these wierd e-mails from people I never heard about discussing
something I never cared about.  

I truly want you to have a great life...but please leave me out of it.
