You can configure whether to enable the following features. By default, all features are enabled. All users can use Spaces, Guest Spaces, People, and Messages.

• Activate spaces
  You can configure whether to activate Spaces.
  For details, refer to the following page.

  If this checkbox is selected, you can configure whether to select the Allow users to create apps that do not belong to any space checkbox.
  For details, refer to the following section.
  Allow users to create apps that do not belong to any space

• Activate guest spaces
  If the Activate spaces checkbox is selected, you can configure whether to activate guest spaces.
  For details, refer to the following page.
  Guest spaces

• Activate People and Private messages
  You can configure whether to activate People and Private messages.
  For details, see the following page.

  • People
  • Messages

You can configure whether to allow users to create apps that do not belong to a space.

Apps are placed either on Portal (top page) or in a space. "Apps that do not belong to any space" refer to the apps that are placed on Portal.

• When the checkbox is selected:
  You can create both apps that belong to a space (in-space apps) and apps that do not.
• When the checkbox is cleared:
  You can only create apps that belong to a space (in-space apps). Clearing the checkbox does not affect existing apps.

Every app belongs to an app group. When you create an app, the app group configured in Default app group is selected. You can change it to another app group. However, apps that belong to a space (in-space apps) are always assigned to the Public app group, and you cannot change this.

If you clear the Allow users to create apps that do not belong to any space checkbox, you can only create apps that belong to a space (in-space apps). As a result, all apps you create are assigned to the Public app group, and you cannot change this. In other words, clearing theAllow users to create apps that do not belong to any space checkbox means you cannot create apps in app groups other than Public (including the Private app group).

If you use app groups other than Public, consider this behavior when configuring the setting.
