what is the point of lingots?
you can not use them up as there are only 5 thing in the shop an i have brought lflirting,idoms and proverbs and timed practice and have brought streak freeze and double or nothing multiple times.
You are supposed to put them on shelves (bookcases to be purchased from your local store) and dust them off at least once a week!!-) Seriously, the XPs, lingots, levels and fluency scores look like incentives/carrots for encouraging people to come back for more... Some of them do attempt to provide some kind of measure for how well one is doing in a specific language.
