Haha I was thinking something along those lines. Like a letter apologizing for his signature's absence, why he never signed them all, and complete with a signature at the bottom. Now *that* would be the Linkin Park I've known and loved for 10 years.
Unfortunately, like you said, they'll never read this and it's almost impossible to get their attention. C'est la vie!

If only we could send em an email (that they would read) and get em to send a bit of wood with his signature or something :P
Good news - Linkin Park CAN hear about this!
It's not a guarantee, but it's still worth a shot.
I would suggest sending messages to their own inbox.
If the Admin see it and think its worthy of the band seeing, or the band log on, you may get what you want.
