From the number of requests I have received by email, Dryden, there are enough people stumped by steps 2-4 of the endgame to qualify it as a legitimate 'secret'.
Why should Elap be treated differently? In a perfect world, he shouldn't. But we already know that there are contributors to this forum that jump at the slightest excuse to make the big REVEAL in the guise of asking a question: "I know that we need to replace 1-2 characters by atomic numbers but I cannot get 21across to work". Rather than "I cannot get 21across to work, please email me if you can help". It happens repeatedly so the posters clearly are getting some sort of pleasure from making the reveal.
What is different this time, is that the setter has explicitly begged for us to not reveal. These setters work hard to give us enjoyment - for little remuneration. The least we fans can do is respect their explicit wishes.
