The shortest tree?
Does anyone know what the shortest tree is by the number of lessons not skills?
I have no idea, but I suggest you ignore the length when picking a language =)
I was just curious. I'm going to do every language. I kind of already have in a way. I just reset my progress a lot. I was level 14 in Esperanto and 12 in Spanish, 11 German, 10 Portuguese etc...
