With the loss of the forum now just a few days away, its only fair that I leave a review that warns people that since buying an annual subscription the service that Duolingo provides has gone downhill. I attended an event and there was no way to give the event a rating. Some could do so but I could not. You can raise a bug but you should neither expect a fix nor any answer from Duolingo. Their "help" center is a black hole for useful guidance. I bitterly regret paying for this alleged service
