What are upvotes?
In the new DuoLingo, it seems harder to get upvotes. Before the change I did some translations and got many. Since, my translations are edited at about the same rate (and often approved) but I do not get upvotes.
I also approve (check mark) many folks' translations but do not know how to GIVE upvotes.
Clarification of the interface would help me.
I think it means someone has rated one of the sentences you translated as good. The sentence with the most good votes becomes the best rated translation and the one other people's translations are rated against.
