[Palindrome] Turning off puzzle-hunters

[Stephen Peters <portnoy portnoy org>]

At Alejandro Sedeno's suggestion, I've just made puzzle-hunters a 
non-mailing-list.... it will remain so until the Hunt gets closer.

Of course, if it's already updated, you won't get this.

(Scott -- when you have an MIT contact person, let me know and we'll 
make sure they get added as an admin for that list).
