Ixion - I will type you at least a little of the reamble:-
Most clues contain a misprint of one letter in thedefinition. The correct letters, in clue order, reveal hints for deriving two versions of a question from the remaining clues. The penultimate element of the first version is one of four that share identical components, as described by a five-letter definition concealed in the grid. These four elements and another five-letter word must be highlighted to show key information relating to the question and an initial representation of the questioner.''One of the fur elements, interpreted differently, indicates which letter of which word in each non-misprint clue contributes to another message. The action it describes must be applied to the letters of the five-letter definition(and theor counterparts) to reveal a representation of that element which must be highlighted in full. Finally, the key information must be modified to provide a consistent rendition. All entries are words in both the initial and final grids.
Well, that's the lot. I really hate to be beaten by any xword, but I think I must give this one best.
