Using shared boarders is a great way to save yourself a lot of work. I use shared boarders in most of my sites, whatever I put in the top, left or bottom of my page will show up on every page, That is perfect for navigation bars, contact email and your logo

Click Format Shared boarders

Be sure to choose All Pages for a new web or if you are adding some pages to a web that you do not need nav. bars on [like these tutorials] click current page

BE CAREFUL if you remove shared boarders from all pages you can use any info that was in the shared boarders
