We consider a general class of models with gauge-mediated supersymmetrybreaking in which the gravitino is the lightest supersymmetric particle.Several qualitatively different scenarios arise for the phenomenology of suchmodels, depending on which superpartner(s) decay dominantly to the gravitino.At LEP2, neutralino pair production and slepton pair production can lead to avariety of promising discovery signals, which we systematically study. Weinvestigate the impact of backgrounds for these signals and show how they canbe reduced, and outline the effects of model parameter variations on thediscovery potential.Comment: 36 pages, LaTeX, 10 figures embedded using epsf.sty (published  version; minor changes in wording
