  Anisotropic and isotropic slow-roll inflation supported by n-forms are
sought. Canonical field strengths and their duals are taken into account, and
they are allowed to have a potential and also, when necessary for slow-roll, a
nonminimal curvature coupling. New isotropic solutions are found for
three-forms. It is also shown that some n-form actions are equivalent to f(R)
gravity and scalar field models with possible nonminimal couplings. Anisotropic
solutions are found for two-forms, generalising vector inflation, however, also
the two-form is unstable during inflation due to the nonminimal coupling to
curvature. We also address the stability of the isotropic background solutions
supported by a triad of vectors .
