As I go through this course I would like to provide feedback, suggestions, or error corrections. What is the best way to do this?
Using the "ask a question" feature under a given lesson is a great way to do so. There are already some questions and answers depending on the lesson. If your feedback or topic is more general, you can open a discussion thread in the Community tab directly (all threads end up there, even if they're linked to a given lesson).
Thanks for taking the time to do that.
