Thanks everyone for all the helpful answers. The designer, Kelli Anderson, is extremely nice and also very busy. I don't think her intention was to be secretive. I've written her in the past and she has always been forth-coming, helpful and totally unpretentious. I admire her work a lot and recommend checking out her portfolio.
Still, I appreciate how much support and information I've gotten from this thread and am going to save it for my files so I can always refer back to it.
