Replace the CMFDefault/MembershipTool.py with one of your own, or edit
it so that the addMember method is protected with a Manager-only
permission.  I've put a request in the tracker for an 'Add Member'
permission for CMFDefault, with patches, at:

  http://www.zope.org/Products/PTK/Tracker/287

Then edit CMFCore/ActionsTool.py so it doesn't display
the 'Join' link to the anonymous user.
