Rebecca,
I updated my home page, trying to implement your suggestions...
Now, I will have to research and create some tier-two pages to link off of these sub-bullet ideas (and more!) from the video...turns out I already had a page on the holographic universe...but it's not a tier two...
...this is the advice that I have been looking for...and will probably lead me to a complete re-design of my tier sturcture...COOL!
THANKS again...I really appreciate the feedback...you are AWESOME!
