This discussion started in the comments to Sudoku (nightmare) The author gave an important hint after some time. I think here is a better place for this.

I can't understand why people are changing the puzzles after a few days. Both ratings are useless after adding a hint.
If there is mistake, it's ok. But just because of the small number of users? You don't know how many users have solved it without registering.
But if some authors often change their puzzles (by adding hints) I will ignore their puzzles in future. If you want the users to notice the intended solution path, why not to describe it in a hidden comment?
I think generally such analyses (and maybe even such puzzles) are not suited best for the portal. It would be perfect for the NED, our (printed) club magazine, which is fallen asleep in the past years. This would be the right place IMO. We have so many new authors here, so many discussions. There would be enough material to revitalise the NED, I suppose.
