- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.

Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
