You can share a widget with specific members, so that only those members can see the widget.
Select the widget in the widget area.
Click the Share button in the Action Button Bar to show the Share sidebar:
Click the button to show the share dialog:
Enter the email addresses in the Enter emails field. Terminate each address with a comma.
Type a message to include in the notifications in the Message field and click Create. An overview of the task appears in the sidebar:
You can click Details to show more information, such as how many members have completed the task. You can archive the task by clicking the menu button
This creates a new Share task for the specific members, and notifies them of it. You might do this if there is a widget that you want to share only with administrators, or if you want to start a discussion among a subset of members.
