  We present a Hartree-Fock study of the competition between disorder and
interactions in quantum Hall ferromagnets near $\nu=1$. We find that the ground
state at $\nu=1$ evolves with increasing interaction strength from a
quasi-metallic paramagnet, to a partially spin-polarized ferromagnetic Anderson
insulator, and to a fully spin-polarized ferromagnet with a charge gap. Away
from $\nu=1$, the ground state evolves from a conventional Anderson insulator,
to a conventional quasiparticle glass, and finally to a ferromagnetic Skyrmion
quasiparticle glass. These different regimes can be measured in low-temperature
transport and NMR experiments. We present calculations for the NMR spectra in
different disorder regimes.
