For those frightened of Xbox Live friend-stalking, the feature's setting can be modified as of today at the Xbox.com Friends of Friends site. For members older than 18, the default setting at the feature's launch will allow everyone to view their friends lists. Gamers can also block the feature entirely, or make their list viewable to "friends only."

In the interest of safety, Microsoft won't allow gamers younger than 13 to enable this feature, and only those older than 18 can set their list as viewable to the general public.
