Gail:
Why would you even read the thread, let alone post, if you don't like discussing peoples salaries. Americans are fixated on this (publications are always showing the average salaries of a teacher, an engineer, doctor, sports figure, etc.). Therefore, I also agree that this is not only an interesting question, but a very informative. We buy from these people and accordingly, I would love to know compensation structure. Salary would also be very interesting.
While they may be on salary, I venture to guess that they are also provided bonuses. DVC has to entice them some way.
