Given the well-known features of the two non-unified standard models, SM and MSSM, a listing of the features of classes of unified models is given, where a GUT flavor symmetry and/or family symmetry are introduced to reduce the number of model parameters. Some general remarks are then made concerning the type of predictions that follow for the neutrino masses and mixings.6 pages, contribution to the Proceedings of the NuFACT'00 Workshop held in Monterey, CA May 22-26, 2000High Energy Physics - Phenomenologytext
