  We report recent results and developments from our ongoing lattice studies of
$\mathcal N = 4$ supersymmetric Yang--Mills theory. These include a proof that
only a single fine-tuning needs to be performed, so long as the moduli space is
not lifted by nonperturbative effects. We extend our investigations of
supersymmetry restoration in the continuum limit by initiating Monte Carlo
renormalization group studies. We present additional numerical evidence that
the lattice theory does not suffer from a sign problem. Finally we study the
static potential, which we find to be Coulombic at both weak and strong
coupling. We compare the static potential Coulomb coefficients to perturbation
theory, including initial results for N=3 colors in addition to N=2.
