First, create a list:(later, you'll see why this step is important)
- under Home section, select Friends on the left pane
- click on +Create a List (for e.g. LIST X), and select the people you want to share limited information with
Second, choose your privacy settings:
- go to Account, and select Privacy Settings
- click on Customize Settings (you'll see a list of things you have been sharing)
- select an item from the list, and click on Custom.
- a pop out window "Custom Privacy" will appear that will prompt you to "make the item you chose visible to" a specific category of people, and/or to "hide it from" a specific category of people. Now you can type LIST X.
