I don't necessarily believe the "subtypes" would necessarily need a chapter to themselves. I see it more as Chapter One: What is Roleplaying? - Definition 1.1 - Different types like LARPing1.2 - Different types like Text BasedEtc, etcIt coul just branch off chapter one instead of giving EACH little thing a chapter of its own. And the Units I pictured more like: Unit One: Fundamentals of Roleplaying (what it is)Unit Two: Maybe something like Character Sheets and such And so forth and so forth.

I like the almost chronological approach you imply here:

A total newbie sees a roleplay, and their first thought is gonna be WTF. A unit explains this.
Next? How do they get involved? A unit explains this: GM-player relationships and formalities, the process of CS's
Next? How do they write a post? A unit explains this: writing conventions, typical rules and courtesies, approaches (to meta-game or not to meta-game)
Next? How do they interact with other players and push the story on? A unit explains this, etc

Literally looking at the PbP chronological process and addressing each topic as it will unfold.

Clearly this is PbP-based (I presume - I have little concept of other RPing, as previously mentioned)
