Based on great comments and questions, we updated the "frequently anticipated questions" to "frequently asked questions" (at midnight last night, on Stephen's laptop).

We have a feeling this will continuously be updated - please let us know if you have any questions, if something isn't quite clear, or just what you're going to do with it.
