  Measurements by the STAR collaboration of neutral pion production at large
Feynman x (x_F) in the first polarized proton collisions at $\sqrt{s}=200$ GeV
were reported previously. Cross sections measured at $\eta=3.3$, 3.8 and 4.0
are found to be consistent with next-to-leading order perturbative QCD
calculations. The analyzing power is consistent with zero at negative x_F and
at positive x_F up to ~0.3, then grows more positive with increasing x_F. This
behavior can be described by phenomenological models including the Sivers
effect, the Collins effect or higher twist contributions in the initial and
final states. Forward calorimetry at STAR has been extended, and there are
plans for further expansion. An integrated luminosity of 6.8 pb^${-1}$ with
average beam polarization of 60% from online polarimetry measurements was
sampled with the upgraded FPD in the 2006 RHIC run. This data sample will allow
for a detailed map of the \pi^0 analyzing power over kinematic variables
bounded by 0.3 < x_F < 0.6 and 1.2 < p_T < 5.0 GeV/c at $\sqrt{s}=200$ GeV. The
expanded FPD has observed multi-photon final states expected to have "jet-like"
characteristics. The transverse spin dependence of jet-like events can
discriminate between the Collins and Sivers effects and lead to further
progress in understanding the origin of single spin asymmetries in forward
particle production. Data were also obtained at $\sqrt{s}=62.4$ GeV for x_F ->
1 to test predictions based on phenomenological fits to earlier STAR results.
Recent results, the status of the analysis of 2006 run data and near-term plans
will be discussed.
