Quoted for posterity below. A couple of other points: * Paragraphs are your friend. Single monolithic blocks of uninterrupted text are the crazy uncle you avoid at family reunions. * They're, their, and there. * You are free to debate to your heart's content the degree of obligation and the degree to which you personally undertake it. Nobody is going to legislate it for you, and I am not saying they should. But I will observe that nobody does tandem BASE jumping or wingsuiting. Thanks, Bob K.
