  Using the facts that in Gauge-Mediated Supersymmetry Breaking schemes, masses
of the right and the left sfermions can differ widely, and the gravitino is the
Lightest Supersymmetric Particle, we show that it is possible to obtain
unambiguous signatures of such schemes in a high energy $e^+e^-$ collider if
one looks at the asymmetries in the cross-sections for certain final states
with left-and right-polarized beams.
