I just called MS yesterday to make my monthly payment by CC (a day late...eeek..i just got back from my Disney vacay...)
Anyway, dues for Kidani are due June 1 and are prorated for this year. I own 160 points and my total for dues (again pro-rated for 2009) is $521.46.
Bills will likely be sent around May.
I haven't set my payments up for withdrawl yet, so I'll have to pay the whole amount for dues by June 1 (easy day to remember my b-day).
