Congratulations, Rob!

At this point, you should be able to work w/ Instantiations tech 
support. You now have correct and complete understanding of what's what 
and where on your system.

I'm sure I speak for the rest of the list when I say that we look 
forward to seeing what you can do w/ Instantiations.

Cheers,
