This list of questions and answers was taken from causal discussion on this and other boards. Although 99% of this material was taken from my comments on this board, I am not the only author who's comments apear here. As such, it is easy to take some of the content out of context, so while reading through the answers, keep in mind that the answers were not prepared with the careful attention that a traditional article would be for publication. Always present any questions that might arise from this content on the HST board for clarification.
