You can request a printed accounting from MS, but nothing will be automatically sent to you. What they send is a bit overwhelming- especially if you have made/changed many reservations.
I always ask for a verbal accounting with each call to MS and track everything in MSMoney. Caskbill is working on a point tracker to go with his
DVC Planner - if you don't have that yet, just do a quick search for Caskbill and the free download information is in his signature.
