Gauge-mediated supersymmetry- (SUSY-) breaking with a messenger scale of the order of ${10}^{15}$ GeV has some interesting features. It can solve the flavor-changing neutral current problem of supersymmetric models with predictions for superpartner masses which approximate those of minimal supergravity models. It can however also lead to theories with novel experimental signatures. For example, we present a model in which the gluino is the lightest supersymmetric particle. We also review the present experimental status of a stable gluino.
