MJG - you have a very interesting paper. Thanks for the links. The elf eh. Hmmm. Gene, if he wasn't hanging together to well 30 years ago, why don't you give him a break and learn about now. He is speaking to what I believe in and I hope that at least a few more people will listen to what he is saying. We have to stop bashing each other on the head and dragging away the bootie.
