Remember My Last - SPOILER

JKR said on her website:
"So: Dumbledore is referring to his last letter, which means, of 
course, the letter he left upon the Dursleys' doorstep when Harry 
was one year old. But why then (you may well ask) did he not just 
say 'remember my letter?' Why did he say my last letter? Why, 
obviously because there were letters before that


Now let the speculation begin, and mind you type clearly, I'll be 
watching


P.S. It has been suggested that I am wrong in saying that 
Dumbledore's last letter was the one he left on the doorstep with 
baby Harry, and that he has sent a letter since then concerning 
Harry's illegal flight to school. However, both Dumbledore and I 
differentiate between letters sent to the Dursleys as a couple, and 
messages directed to Petunia ALONE. And that's my final word on the 
subject - though I doubt it will be yours :)"

Tonks now:

So the letter that he left with Harry that night was to PETUNIA. I 
assumed all of this time that it was addressed to both of the 
Dursleys, but it was not. And there were other letter before that 
one. So this is telling us something.. perhaps Dumbledore, as I 
mentioned before, knew that LV would try to kill Harry and that Lily 
would give her life to invoke the ancient magic (charm). It was 
arranged by DD and Lily and probably Neville's mother too, in case 
LV came for Neville first. I think someone else mentioned that DD 
probably wrote to Petunia to prepare her for the possibility. But 
again he calls her Petunia every time. So he must have know her long 
ago when she was a child and her sister was going to Hogwarts. 
Humm...  what does it all mean?  Where is that 6th book?!!! (I am 
going to have to learn to bi-locate so I can peek over JKR's 
shoulder while she writes!)
