Reply as requested: 

It is alluded to in CoS ch. 17 (US paperback p.313)

Tom and Harry are chatting in the chamber.  Tom is doing the 
obligitory eight-page ramble of exactly what he had been up to all 
book to toy with his intended victim and inform the reader.

He tells Harry about how Ginny had told him all about Harry, at which 
point he decided he wanted Harry and was going to use Ginny as 
bait.  "So I made Ginny write her own farewell on the wall and come 
down here to wait."

As McG correctly told the staff that it was Ginny in the chamber, I 
guess we can figure that Ginny signed the note.  (Or wall, as the 
case may be)  

What I want to know now, is what did that note say?  But, alas, we 
are not told.

Ginger, who is always happy to answer obscure questions, as long as 
they are actually obscure and stated in canon.  (I'm not much of an 
original thinker, eh?)
