So I'm thinking maybe the Guestbook could be an actual real book, with hand-written messages from you guys. Like if you were to write something with a pen and paper, and send it to me. Then I stick it in a book.
Sorry, thinking out loud here... I'll do a test...

Right, here's how we can do it... (click for big pics)

You write a message...

 

...and email me a photo of it.

 

I'll print it...

 

...and stick it in the book.

 

Ok, please get a piece of white paper and a biro. Write today's date, one or two sentences, and your name. Try to write it in a square shape, to keep the book looking neat. Take a photo and email it to commentsGOAWAYBOTS@richcolour.com (remove the capitalized part). If you can, send the photo 'Original Size' and not reduced quality. My printer can only do black and white, so put away your Crayolas.

Yeah I think this'll work! First person to sign the book is allowed to write "FIRST" and is the winner.
