Admin issued a topic drift alert back in message 181.
My impression - Schraf is covering some interesting stuff, and it is getting lost in topic it doesn't belong in.
I strongly suggest Schraf plug this material into a new topic. I guess it could go directly to the "Coffee House", unless she thinks it better in another forum.
Maybe it's time to close this topic down, but I'll leave it open.
