Autofocus Help Please, Adding Links to the Navigation

Hi everyone, I’m in need of alittle help. I’m trying to work with the Autofocus theme and I can’t seem to add more links to the Navigation or Sidebar at the top (where Home and About etc are). I would like to add a Portfolio link that will open a popup window OR just add the link (whichever method I can learn first). I read on Allan Cole’s webpage this:

Sidebar

The sidebar for this theme is included as a template for use on an ‘Archives’ page. To activate the sidebar, create a page called ‘Archives’ for example and select the Archives Page Template. This template pulls in the 2 sidebars that sit right on top of each other.

I did this, but no change. In fact, it just gives me the template layout. Am I missing something?

Please help and thank you.
