Quote - I
I run into this more often than I'd like, so I tend to be sensitive to it. I err on the side of assuming you know more, because when I assume the reader knows less, quite often the reader gets pissed at me.

I here you loud and clear on that one as well.

A bit of a doubled edged sword here.

If I am looking for new information I take no offense to starting at the beginning. After all I am the one asking for the instructor's time and knowledge.

No matter how you do it, i for one am a great fan and much appreciative of all the teaching you offer to the Poser Community.

I am having lots of fun with your IDL Hallway concept.
