Week 2- Muddiest Point

I'm sorry for being quite slow, but I was confused by the Discussion Point. I guess the discussion topic displays the readings for the discussion point, even though there are two different names for the assignment being used. The discussion topic isn't an assignment, though- right? It is just something you can do if you want to. Is that correct? But we put the responses in courseweb by Tues.- like we do for assignments, yes? Also, where should we post the digitation activity due on Tues.?
