For example, by sharing a friends-only journal on Facebook,
Twitter, or MySpace, only your friends will be able to view your
journal. If they are not a MedHelp friend, the link will take them back to your profile. Sharing a post from a private user group will link to the private group's join page, keeping the group's content totally private unless the user joins and access is granted. Posts in forums have always been public and remain so.
