I can not seem to find the next lesson after the one named "Hi" What do I have to do to get it to come up?
"Hi" is the final lesson. If you've completed that and the quiz right after it (the castle icon), the best you can do is start redoing the lessons until Duolingo expands the course or seek out other resources to continue your learning.
Thanks for the info. This is the first time I have completely finished a Duolingo course. I got a lot out of it and am looking forward to your expanding it.
