The importance of measuring the non-D D decays of the ψ'' = ψ(3770) resonance is discussed. These decays can shed light on a possible discrepancy between the total and D D cross sections at the ψ'', and on a proposed mechanism for enhancement of penguin amplitudes in B meson decays through charm--anticharm annihilation. Measurements (including the ψ'' line shape) in states of definite G-parity and in inclusive charmless final states such as η' + X are found to be particularly important.
