Query: GUT Implications from Neutrino Mass   An overview is given of the experimental neutrino mixing results and types of
neutrino models proposed, with special attention to the general features of
various GUT models involving intra-family symmetries and horizontal flavor
symmetries. Many of the features are then illustrated by a specific SO(10) SUSY
GUT model formulated by S.M. Barr and the author which can explain all four
types of solar neutrino mixing solutions by various choices of the right-handed
Majorana mass matrix. The quantitative nature of the model's large mixing angle
solution is used to compare the reaches of a neutrino super beam and a neutrino
factory for determining the small U_{e3} mixing matrix element.
