For more information on sharing: http://thalia.mit.edu/help/index.html?quickstart.html.Note: Some customers need to restrict materials to MIT community use. It is possible to designate an entire domain as MIT-only (but not not individual items). These domains will require MIT Touchstone authentication before allowing users in.
