Still havent' found an answer to it. I was hoping admins can shed light on the above? If I miss a single day, I don't see the missed cards again and there is no way to setup vacation timer or revisit the days I missed the cards.

I now use these cards post-ABIM to not forget any facts (while adding additional facts to the memory bank) and while they are helpful....not being able to re-visit the missed cards is fast making me reconsider continued subscription to the flashcards.

A small upgrade to fix this issue and maybe add few features will go a long way in users continuing to use them for ongoing learning.
