edit: It occurred to me that making this post might have violated some necroposting rule that I'm unaware of. I'm not certain of the etiquette here; was this impolite? I just thought it made more sense for someone who reads this discussion for the first time to have a link to where it was continued.
In general commenting on old posts in encouraged; for indexed posts like this forward-linking is probably best.
- 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.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.

It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
