We consider the experimental signals that can arise in a general class
of models with gauge-mediated supersymmetry breaking in which the gra
vitino is the lightest supersymmetric particle. Depending on which sup
erpartners decay dominantly to the gravitino, several qualitatively di
fferent possibilities arise for the phenomenology of such models. At L
EP2, neutralino pair production and/or slepton pair production can lea
d to a variety of promising discovery signals. We investigate the impa
ct of backgrounds for these signals and show how they can be reduced.
