I didn't read through the above so forgive me if some of this is repeated.

Yes, I would buy a Poser 5 book provided it was written in depth and in laymans terms. I didn't know you wrote the manual so again forgive me for my opinion but it isn't enough. Example, I tried to learn the cloth room through the manual and while it explained each dial and part of the cloth room, it didn't give any example for actually getting a cloth to do something. My cloth kept falling to the floor and the manual did not explain it well enough. What I've been able to get done in the cloth room is most definitely not due to the manual but to the community. Same with the face room and hair room. Things were described but there was no examples to follow. That's the only way to learn.

I recommend:
Detailed steps
More photos
A few "how to get this effect" tut' for the cloth room, face room and material room.
A more detailed index

I'm sure I have more ideas but I'm only on my second cup of coffee. :)
