To start, login to Admin Mode.
There are two ways to change the order of pages in your websites.
The first method involves going to the page to be moved. For example, if you wish to move the location of the "Contact" page, then click on the "Contact" link in the navigation area so that it becomes your 'current' page. Hover over the "Page:" link near the top of this page. This will cause the Page Menu to be displayed. Hover over the "Move This Page" option of the Page Menu and a sub-menu will be displayed. If you wish to move this page earlier or higher or sooner in the navigation, then click the "Before" link on the sub-menu. Alternatively, if you wish to move this page later or lower in the navigation, then click the "After" link on the sub-menu.
The second method of changing the order of the 'current' page has to do with placing the page as a sub-page of another page. To do this, hover over the "Page:" link near the top of the page to get the Page Menu. Click the "Edit this Page" link. On the resulting form, change the "Path" field to the new 'parent' page for the current page. After you click the [Save Changes] button, then the current page will be moved to live below or under its new 'parent' page.
