Design or Architecture using Master Pages

[Sridhar Panatula]

Hello ,
I am writing up a service for existing website

Idea is when somebody click on an item in their Menu links they are taken to
my site

To personalize I am trying to use Masterpages on my site look like the
original site with they permission.
I am able to display Banner/Logog etc., on the Top, and other paraphenalia
in the Bottom of my page

But how do I get Left Side Navigation bar instead of embedding it in every
page?

Thanks
Sridhar
