All the info's at the site but the basic gist is that you can send anything in. Notes, poems, stories, photos, artwork, anything you want, just be as creative as you want.
I'll collect everything together, bind it up and give it to Jewel when i attend the convention. If you'd like to send anything in please email me at webmaster[at]jewel-staite.net and i can pass on my mailing address as to where you can send your stuff in for me.
If you have any questions let me know :)
