Freeform Universal (Second Edition)

From the introduction: This is the Beta version of Freeform Universal, second edition. While it has been in development for a very (very!) long time, it still isn’t complete. There are sections missing, a bunch of bits that may need a re-write, and other parts that may be a compromise too far. It’s best to consider this Beta version a nice-looking first draft, useable, but in need of polish. It has been built on 10 years of play, discussion and enthusiastic support from the FU community, but there is always room for improvement.
