Create Panel Pages
You may want to create panel pages for your group.
Use panel pages to organize your content in an attractive and informative manner. Each panel page becomes a tab when viewing your group. Different layouts can be chosen to best display the content for each panel page.
After you create a panel page you can then "Change the Layout of your Page" and add content.
Content can be added in 2 different ways: "Widgets" or "Custom Content".
Widgets enable you to quickly add automated content. Custom Content provides flexibility to manually add content (e.g. lists, links, descriptions, definitions, etc.)
