Query: Mirzakhani's Curve Counting   Mirzakhani wrote two papers on counting curves of given type on a surface:
one for simple curves, and one for arbitrary ones. We give a complete argument
deriving Mirzakhani's result for general curves from the one about simple ones.
We then sketch an argument to give a new proof of both results -- full details
and other related matters will appear in a book we intend to write.
