From the Top Nav Bar I added a new page to the site and used copy current page.
Completed the page and Published it. All is working fine but can I make the
necessary changes to the Top Nav Bar to include new page created? I am having
difficulty finding out how if you can at all.

Top Nav Bar:

Blah1 | Blah 2 | Blah 3 |

| Stuff 1 | \
| Stuff 2 | Side Nav Bar
| Stuff 3 | /

New page created is "Stuff 4", and is what I need to add to the Top Nav Bar
"Blah 3"

If you have to update the source of a page in Notebook can you then update the
source on your site with Contribute? If so what are the procedures?

Hope this makes sense and appreciate your time and assistance.
