You can create your own Custom web pages in the Content > Site Page Structure page. After you have created a Custom page, to edit the page, go to Content > Page Edit. The Page Edit page lets you edit the content area of the different pages available on to your organization.
- Click on the drop down arrow to select the page you want to edit.
- The currently saved content will display in the Edit Page Content area on this page.
- Modify the content using the tool bar that is available -- like you would edit a page in MS Word.
- Click Save when you are done.
