I read somewhere that the persons running the society have had health problems. My guess is that the society is in trouble because of lack of management. The web site is a disgrace and has not been updated in many months. I did not renew my own membership in the Heinlein Society, although I did agree with its principles.
My guess is that the contest will end soon, although it may end badly for everyone.
RAH would have had much to say about any editor that kept him waiting for a year!
