Can't seem to get enough of the flashcard exercises. This feature wasn't there when I used Fluenz a couple of years ago. I now find that when I complete a session I go directly to the flashcards for the last 2-3 sessions and practice-practice-practice. I am still doing review and working my way through what I had previously done, but I am retaining more and I think it is because of the repetition offered by the flashcard feature. Thanks for that, and I think you should emphasize it more in your promotions.
