You're opening an "old" sore with this question. I
think Virtools is very aware of the need of a
more thorough documentation and I think they will try to
fix it with the next version.
Until now, there's only the manual and some sample files
in the techcenter.
If you have a specific question, go to the forums at the
swap meet.
The guys from Virtools are very
responsive.
In an earlier Newsletter, Virtools said, if you buy now
you will receive a free upgrade.
