By the way Gwenog, I know its probably not true, but I like to think that Hagrid replaced Snape as headmaster, simply because he deserved it.

7. Goblin and elf magic works differently from human magic. Then why was Griphook unable to escape Malfoy Manor through apparition as Dobby did?

8. George's ear was severed by Sectumsempra, dark curse so couldn't be reattached. But Snape fixed up Malfoy easy enough after Harry cursed him

Surely it must be snape.
In OotP petunia says she heard lily and "that awful boy" talking about dementors. In DH we see the overheard conversation between snape and lily about dementors.

I think the howler was from dumbledore. At the time of reading OotP I thaught it was about the letter dumbledore left when harry was left with the dursleys. But now I am not too sure. It could very well be about her rejection from the magical world. It fits in certain ways, I think this is an answer we will have to find out from JK rowling herself.

Hmm, well from what I remember in the book harry does touch it and it burns him, but I think that when he left the vault the curse was lifted, so the curse would only be active in the vault. Or maybe it was an honest mistake by JK rowling. I mean it must be impossible to write a ?609? page book with no mistakes??

Hope this answers your questions.

FURTHERMORE

I have a question, I thaught we were going to be told about how people went about being ghosts. (how they do it basically.)

I don't remember being told this in the book.

Also after voldy died, would the death eaters still have the dark mark tattoo? Or would the spell end with the spell casters death?

I think I can answer the question about the person who does magic late in life.

Ariana Dumbledore!

She was mentally unstable at the time when she should have been at Hogwarts and only really did magic when she heard Albus and Aberforth arguing.

In my opinion, Arianna killed herself when she uncontrollably used magic, may Albus rest in peace.

Yeah, I think that's true! I expected it to be a character we've already met beforehand. Anyways, I have more helpful facts for you. Again, these are all from a reliable source, saying JKR said these in an interview.
