Since the response to IdlePoser was a bit slow, I assume it might not be clear for many what it can do and how to use it. Hence a short 7 page tutorial!
The tutorial is a free download....shameless advertisement for IdlePoser, which is still in EarlyAccess. As usual, it's released under CC BY-SA license.
