My husband and I each received mail yesterday with the details (diamond level - although the mail says platinum as at the time of sending we were ~300pts short). Looks to me like they're trying to weed out players that show up once a week and play for 200 pts a trip to make diamond. Understandable I guess. If you've been to AC, you know the diamond lines at the restaurants, etc, are longer than the gold!
I just wish they'd have joint accounts the way Tahoe used to.
