I tried and completed this for the first time this week. I so wish that this code o silence would prevail on some of the other, shall we say, tougher crosswords. More helpful clues, certainly, but I find it extremely galling to have worked hard on, say, Mephisto, to look at a thread later and find the answers given.
I have noticed that on some of the easier xwords, for instance the Sunday Times cryptic, that over the course of a day you could complete it with the answers on various threads.
