I don't get it. How about a hint for non American Readers?

It's not American slang; it's internet slang, I guess? (The following is an explanation for anyone who both reads MoR and these discussion threads but isn't familiar with fanfiction in general.)

"Ship" is a term of art in fan communities deriving from "relationship" that indicates you think two fictional characters in some fictional universe should be together, e.g. "I ship Harry and Hermione" means "I think Harry and Hermione should be together." A substantial amount of fanfiction is centered on shipping, e.g. you ... (read more)

5LauralH8yIt's just fanfic terms: "shipping wars" are people who argued over, say, Harry/Hermione vs. Ron/Hermione, and "OT3" in that case would have been Harry/Hermione/Ron. (The original acronym was OTP=One True Pairing.)

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 87The previous thread has passed 500 comments. 

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.) 

The first 5 discussion threads are on the main page under the harry_potter tag.  Threads 6 and on (including this one) are in the discussion section using its separate tag system.  Also: 12345678910111213141516, 17.

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.
