just starting out with razor and I need some help

hi there,

I have setup my mail server like so.

http://www.yourhowto.org/content/view/65/9/

And now i'm trying to get SpamAssassin working with Razor, this is what I
have done so far.

http://www.yourhowto.org/content/view/74/9/#razor

with the command

razor-admin -register -user= [email protected]

Do I have to run that for every user on the system? or just once? also
what lines need to be added in the /etc/mail/spamassassin/local.cf file to
make SpamAssassin use razor? Do I have to sign up or pay to use razor? any
I missing anything out?
