The Guide still needs to be updated to explain how category-specific administration works. I'm hoping Leora or Opi will work on that.
We also need to start splitting this document up into multiple Guides soon. I think the best way to start is by moving information for privileged volunteers into a separate Guide. I'll take care of that. Later, specific departments like Customization will probably submit enough policy material to justify creating additional, category-specific Guides.
