It’s always nice to see another user starting WK as an advanced learner.
I can absolutely relate to the filling of holes in one’s knowledge.
Hm, I feel it’s been much more nuanced recently, but I might biased because I only hear about those discussions when someone links my own thread (shameless plug) in those discussions. 
Anyway, my own thread is closed and the message bears repeating, so it’s always good to have more threads about it.
