I know it has been mentioned which forum to go to to learn how to get Ray Bradbury a letter or drawing or something, but I can't remember where it was. Could anyone tell me?

And would Ray appreciate a collection of creative writing that overviews his life and enthusiasm and imagination? (for his own enjoyment) Or would he rather just get a note from me saying how much I like his works because he wouldn't have enough time to read anything I wrote?
