More on HG Friends. Added Delete(string, string) across the board. Added security to friendship identifiers so that they can safely be deleted across worlds. Had to change Get(string) to use LIKE because the secret in the identifier is not always known -- affects only HG visitors. BOTTOM LINE SO FAR: HG friendships established and deleted safely across grids, local rights working but not (yet?) being transmitted back.
