Meursault, I heard on the grapevine that the alternative portrayal of the gallows was accepted, but I won't know for sure until the personal statistics are issued next year.
I've generally found the marking to be very fair, and alternatives, if justifiable, are normally allowed.
You're sensible not sending entries in. It saves a lot of last-minute anxiety about trivial issues.
I can see why this grid must have been difficult to construct. Looking at Bradford's list of thematic items, there are not many to be found that allow the insertion of a letter to make another word. Hence, presumably, the three examples that simply have the unlovely item attached rather than crossing them.
