Changes to JKR official site - or bad memory?

I thought for sure that a year ago I got two ideas from JKR's 
official website:

1) It was highly unadvisable to make any living creature a horcrux, 
and impossible to make a *person* a horcrux, and

2) In the Fidelius Charm, if the Secret Keeper dies (oh blin - was 
it the Secret Keeper or the subjects of the FC? oh dear; I wish I 
could find where I read this!), the secret dies with him/her -- and 
I thought she explicated this further by saying that no one new 
could be brought into the secret.  This one seemed to be written 
post-PoA, as no reference was made to DD being secret keeper for the 
OP HQ.  (Two problems: if she actually said this, there are problems 
for at least one of the FCs we know about: How could everyone find 
the Potters' house in Godric's Hollow, since PP was still alive?  
Unless, of course, it is that if the *subjects* die, then the charm 
breaks and everyone can find the hidden location.  Second problem: 
was Hermione just plain wrong, and created greater difficulties than 
necessary, because she couldn't actually bring Yaxley into 12GP?)

I remember studying her website last year before DH came out, and 
while I wasn't a member of this group, I was formulating theories of 
what would happen in the final book.  Some of my theories were based 
on what I *thought* was canon.  Now I can't find these two points on 
her site.  Did I actually read these things on her website, or did I 
read them somewhere else (eg, an interview on Mugglenet), or did an 
imposter write them, and I believed she actually said these things?  
Does anyone else recall reading these two explanations, and if so, 
where?

Thanks,
