You can easily create new pages in your web site.
To create a new page:
Navigate to the section of your web site in which you'd like to add the new page.
NOTE: SharePoint will add the new page to the section you are in when you complete this task. Make sure you are in the appropriate section before you move to step 2.
Click Site Actions, and then click New Page
The New Page window opens.
Type the name of your new page in the New Page name field.
TIP: Name the page something short, concise, and logical to the page content, keeping in mind that the page name will be displayed in the URL for the new page.
The new page opens in Edit Mode
Your new page is created, and opens in edit mode.
NOTE: The Page Headline and Page Subheadline fields are automatically populated on your new page. Make sure you replace the auto-populated text with the title and subtitle of your page or your new page will publish with "Page Headline" and "Page Subheadline" in the title sections.
TIP: If you do not see your new page in the left navigation, refresh the page.
