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.)
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
When Dumbledore showed Harry the comments he made in her potions textbook the potion he was commenting on was the Potion of Eagle's Splendor, which is the potion for an increase in the Charisma stat (which technically doesn't have to involve appearance but is often considered correlated with it) in 3rd edition Dungeons and Dragons.
ETA: The other things which makes it more suggestive is that the potion Petunia took was dangerous or rare, else more witches would also have permanently improved their appearance, and a normal potion listed in the standard 5th year text presumably wouldn't be; The suggestion presented was thestral blood, thestral blood was implied to have a role in the permanence of the Cloak and as Harry deduced that potions making isn't creating magic but reshaping that which is there some component in Petunias potion must have an association with Permanence.
thestral blood was implied to have a role in the permanence of the Cloak
I know the blood is used to mark the Deathly Hallow symbol on the Cloak, but could you remind me where it says this relates to permanence? I rather assumed that, since thestrals are invisible to all those who have not seen and comprehended death, the relevance of thestral blood was to do with death and/or hiding from it.
the potion Petunia took was dangerous or rare (...) and a normal potion listed in the standard 5th year text presumably wouldn't be
Dumbledore scribbles nonsense in the margins of the Eagle's Splendour recipe of Lily's book =/= Dumbledore helps Lily brew Eagle's Splendour. At most, it confirms that Lily knew how to brew said potion when she was in her fifth year.
Furthermore, even if Dumbledore helped Lily brew a fifth-year potion, there is no reason to believe that he did so secretly, or that he had ulterior motives beyond helping her. Lily was a student he paid rather creepy special attention to - why wouldn't he help her with a special project?
