Yes. You can add or remove friends from any of your lists. You can also adjust the details that are used to create the list - like the age of friends who went to your school who may be classmates of yours.

To change this:

1. Go to your lists page (Home > Lists > More)
2. Click on the name of the list you want to edit
3. From the On This List section in the top-right corner, click (change)
4. Pick your own list restrictions (ex: friends living within 20 miles of San Francisco)
5. Click Save

When you add someone to a smart list, they can choose to add that information to their profile (timeline). For example, if you add one of your friends to your work list, they’ll have the option to add that company to the Education and Work section of their profile (timeline). You should see a reminder about this the first time you add someone to one of your smart lists. Note that even if your friend decides they don’t want this information on their profile (timeline), they will still be added to your list.
