<p>You must select a group to deny permission to posts with the "private" token.  Do this on the groups page.  Usually, you'll want to <em>deny</em> the "private" token to the "Anonymous" group, to prevent users in the Anonymous group from seeing posts with the private token.</p>
<p>On the post creation page, a new checkbox labeled "Private Post" will appear in the settings area.  Check this box to make the post private.</p>
