Julia: YES! I am left scratching my head about how some of the questions get picked. I think some people are coming at the course from the very basics and the staff is pulling the most common questions to try to keep them engaged. From what you've said, your questions are deep and may require more time to answer. Maybe they will be answered in later lectures as they seem well thought out and detailed. Would you post them here? You know you can always get quick feedback on permies.
Some of the PDC questions are hard to read though...
Part of me wonders who pays that kind of money and doesn't have a clue at all about what they are getting into? I'm not dumping on people, I just thought most people would have a lot of the basic terminology down pat before beginning such a course. I salute anyone who just dove in head first. It just takes a lot more commitment to get up to speed.
Then part of me wonders how many trolls are lurking there just to make a mess.
I like the bit about a 40 meter wide herb spiral. You can tell he deals with a lot of magical folks with good intentions and bad planning skills.
