How do I create an area of the site for Board Members only?

To create a Board Member section of the site, first, you need to create a menu that all the Board member pages will live under:

1. Log into the site with an admin account.
2. Click on "Administer Site" in the menu.
3. In the left menu, click "Margin Menus & Links".
4. Click the "Create" button.
5. Enter a menu name, such as "Board Members", then set the Access Type to either "Administrators" or "Editors" depending on the group that you have assigned your board members to; then set the active state.

After your menu is created, you can start creating pages (or assigning existing pages) to the new menu.

1. In the left menu, click "Site Content", then "Webpages".
2. Click the webpage that you'd like to edit or click the "Create Webpage..." button.
3. Next to the "Menu" drop down, select "Board Members" or the name that you used in Step 5 in the above section.
4. Click "Save"
