Query: Noncommutative Two Dimensional Gravities   We give formulations of noncommutative two dimensional gravities in terms of
noncommutative gauge theories. We survey their classical solutions and show
that solutions of the corresponding commutative theories continue to be
solutions in the noncommutative theories as well. We argue that the existence
of ``twisted'' diffeomorphisms, recently introduced in hep-th/0504183, is
crucial for this conclusion.
