I summarize recent developments in spectrum calculations using Kogut-Susskind quarks. Theoretical developments include one-loop computations with improved actions. I present some recent simulation results, mostly from a MILC collaboration project using three flavors. Effects of dynamical quarks are clearly seen in the isovector 0++ meson propagator and in the mass ratio "J".
