Hi disfan!
CathyCanada is probably the person to answer this for you and she is gone for a few days. She did suggest that people PM her with questions, so I guess that would be your best bet.
See you at DIS Con!
Cathy just got back and I am sure she is doing some catch up on emails.. etc... I have messaged her and I am sure she will enlighten us when she has a second..
