If you want an extra layer of security, you can
limit who can view your Profile and comment on your wall as well as
limit who can see your Profile Pictures.
To do any of these, click:
Profile > Modify Profile > Ultimate Profile > and then tick or untick the following:
- Only Buddies can view my Ultimate Profile
- Only Buddies can post comments
- Show my pictures only to Buddies and Admins
Allowing only Buddies to view your Profile Pictures is helpful if you want to post more private pictures to your Profile but you want to choose exactly who can see them.
