If you need information on the gory details of Poser's inner workings....

Content Creation in Poser 5 by B.L. Render: Do not pass Go, do not collect 200 dollars, buy this book
now!  While it's listed in Amazon or Barnes & Noble, there are usually several copies on eBay for under 20
bucks. Get one. I can't say enough about it as it cleared up ALL of my CR2 questions. An invaluable resource
despite being for an older version of Poser. Think of it as a combination of the Torah, Koran, Bible and the
Bhagavad Gitafor Poser. Every CC I've talked to swears by this book.  She even details the rigging of
mechanical items including the rigging of a piston. The author is sadly, no longer active in the community but
will answer polite emails.

And since you brought up the point regarding religion, I spent many years fighting my way free of a childhood indoctrination into religion.  I've become a real, honest to goodness scientist (anthropology) at the ripe old age of 60 and can now see religion for the hocus pocus, mumbo jumbo that it is.  I trust we will all agree to not ever bring this subject up again.?

I'm not familiar with your previous work and am wondering what sort of things you intend on making.  I also have the desire to make stuff.  Along the way I'd like to document my progress and make a proper tutorial.
