Sorry, I've been waiting until I actually read the story before replying. But now it's approaching a week later and I should thank you for the link even if I haven't gotten around to reading it yet! I will read it soon, rest assured, and comment on it. It's printed out and sitting on the nightstand.
Thanks again!
