setting up a vertiual server

[Baloff]

Hello
after creating a vertiual sever nnspool, don't I need to change the set up
in my .gnus.el file? it is currently

**********************************************************************
;;C-h i m gnus for more info about this file
(setq gnus-select-method '(nntp "news.iprimus.com.au"))
(setq gnus-select-server nil) ;should be nil be default but just in case
(setq gnus-nov-is-evil nil) ;quicken grabbing article headers
(setq guns-read-active-file nil) ;prevent requestion the entire active file
(setq gnus-check-new-newsgroups nil)
(setq gnus-check-bogus-newsgroups nil)
(setq gnus-treat-hide-headers 'head ;cut down the header to minimum
      gnus-treat-hide-signature t
      gnus-treat-hide-citation t)
**********************************************************************

I was reading the NNTP node in the Getting News node, it is a bit hard for
me, it talk about hooking a function to variable and the else...
from what I understand, I need to redirect the "news.isp.com.au" to that
vertiual server, so I guss that would be
(setq guns-select-method '(nnspool "news.isp.com.au")) ??

help

thanks
