Since there is no way for users to specify to use even their own preamble for forum posts (which we might want to change...) we should probably include some simple macros, like \Z, \R that people might want to use across PM. I had put together a nice common preamble in my work on the One Big Book version of PM in 2005 or so, maybe I'll be able to find that.
