currently, I can have one book namespace. but usually one book namespace is not enough.

You can only have 1 book namespace. You can create sub-forums under the Book namespace to organize your books more.

If you are using your Book namespace as only 1 book, this is not proper usage. Each page in the namespace should be a different book.

I can't figure this out. I have a forum named 'Wiki' and I'm trying to get all subforums to work as books. I have the main forum called 'Wiki' designated at the Book namespace. Some sub-forums are not even showing up. It's very confusing.

If you're not seeing the sub-forum as a choice when creating new articles, make sure the sub-forum has the wiki enabled in their forum options.
Make sure the Display Order is not 0, as this hides the sub-forum from the forum list.
If the parent forum had custom forum permissions, it's possible the permissions were not inherited when you created a sub-forum. Check the sub-forum's permissions to be sure.
