  Field theory and gauge theory on noncommutative spaces have been established
as their own areas of research in recent years. The hope prevails that a
noncommutative gauge theory will deliver testable experimental predictions and
will thus be a serious candidate for an extension of the Standard Model. This
note contains the results for expanded gauge theory actions on a noncommutative
space with constant theta, up to second order, together with a discussion of
the ambiguities of the expanded theory and how they affect the action.
