Is the message that:
1. People shouldn't ask here for help with
charity quizzes.
2. People shouldn't ask here for help with
charity quizzes until a certain point after the issue date or before the closing date.
3. People shouldn't ask here for help with
prize crosswords or quizzes until a certain point after the publication date or before the closing date.
4. People shouldn't ask here for help if the setter/publisher of the crossword or quiz has requested that they don't.
...or all of the above, some combination of the four, or something else?
