I'm not sure this is the right forum, but... about the mysteries FAQ

The website "http://www.i2k.com/~svderark/lexicon/faq/index.html" 
has a FAQ. (i'm assuming this group is related. if not forgive me.) 
There are several 'mysteries' listed there that seem (to me, at 
least) not to be so mysterious. I'm listing some possible answers 
below. Some me may be more plausible than others, but what do you 
think?

"How does Hagrid "fly" to the Hut on the Sea? On a broomstick? If 
so, where is it the next morning? Superman style?"

Maybe Dumbledore apparated him (a kind of flying?)

"Hagrid and Harry take the boat that the Dursleys used to get to the 
Hut on the Sea in Chapter 3 of SS. How then do the Dursleys get to 
land?" 

With some difficulty. They would have to wait for the man who rented 
it to them to show up, etc..

"How can Sirius Black apparently openly own his flying motorcycle 
and yet Mr. Weasley's flying Ford Anglia is illegal? "

When was the law passed? There is a comment in CoS to the effect 
that Mr Weasley himself wrote the law in question.

"What was the size of this motorcycle? It was described as a giant 
motorcycle at one point, but if so, how did Sirius ride it? If it 
wasn't giant-sized, how would Hagrid have ridden it? "

A magic motorcycle might change size to accomodate the driver.

"Hermione indicates on the Hogwarts Express that she has already 
tried a few simple spells for practice. Why didn't she get a
letter 
from the Ministry of Magic as Harry did in CoS? "

Perhaps the rule only applies after one has enrolled in the school. 

"How does Dobby (then the Malfoys' house elf) visit Harry in the 
hospital wing after the Quidditch match? "

This one has to be a real error. Consider when Dobby visits Harry in 
the Hospital Wing. There is a snap! and he's gone....

In SS, Harry's glasses are supposedly "taped" together in
the middle 
because they'd been broken by Dudley so frequently. In CoS, Harry 
breaks his glasses (which appear to be whole) when he lands in 
Knockturn Alley. Were his glasses repaired at some point during SS

By Hermione after the yellow scabbers charm fails (at least in the 
movie this is so, although I don't find it in the UK version of PS).

"Why would Lupin not transform when the boggart turns into the moon? 
If it's because it's not really the moon, then why does Harry hear 
his parents' dying moments and faint when the boggart turns into a 
dementor? "

Trauma? Boggart attempts to frighten you. Lupin would be frightened 
of the full moon but not physically transforemed by it. Harry, on 
the other hand, because he's been affected by Voldemort's attack, 
mentally 'relives' an experience he would not otherwise remember.

"If it's available in bottles, why was Lupin so surprised and 
suspicious when Harry says Ron and Hermione brought him some back 
(explaining why he'd tasted it before)? "

Believing that Harry had not had an opportunity to visit the village 
he thought it would be a new experience. Harry's instant and 
delighted recognition would make him suspicious. On the other hand, 
Rowling has a knack for describing an event or reaction according to 
how Harry and his compatriots perceive it. Thus Lupin's "reaction" 
to Harry's recognition of the Butterbeer could be no more than a 
description of Harry's sense of guilt and fear of discovery for his 
unauthorised trip into town.

I haven't finished my 3rd reading of PoA and GoF, so I have no 
comments on the remainder of FAQs.

Sorry if this duplicates other msgs; it just struck me as probable 
answers to these particular questions.
