Entering year two of Part D

I was just wondering how the first year went. I know in the beginning, the individuals at the MH/MR agency I work at had a hard time. They were either covered by two different PDPs or not covered at all , or were paying the full price for medication even though they were supposed to received subsidy . Now that year 2 of Part D is beginning and open enrollment is right around the corner (November) I foresee the same headaches again. How did the change affect the people at your agency and do you see the same problems or different problems for year 2?
