I have the Diamond level for 4 categories so far. 3 of them, Letterboxer, Environmental and Calendar, show that there are more required for the next level.

I have completed my Calendar with 366 days. It shows 646 in the 'Now' column and 86 (23%) in the remaining column. Please let me know what calendar you are using because if a year is 732 days long then I would like to be able to say I'm really 31 years old. [:D]

Letterboxer - Current 51, remaining 49 (98%)

Environmental - Current 14, remaining 10 (83%)

Diverse - Current 10, remaining '-' (I've actually found 15 different types plus lab caches)
