There is a puzzle concept I have been working on a few years, off and on.
It is related to some I have seen on the cover of Games, a sort of Tic-Tac-Toe that has 9 or 16 images, with the idea being to find a common theme for each row, column, and diagonal.
My twist is that it would be limited to the universe of official US postage stamps.
For example, I have a theme, and most of what I need to complete it, but I am a couple of images short. I don't know what stamp to use for the final two items. They could be found, I suppose, by coming up with a pun, a straight image, or some idea that eludes me.
I am not suggesting, "Hey, I should post this kind of puzzle on PSE!", for which anyone who disagrees then decides to "downvote." (Sorry if anyone feels this is "passive-aggressive," but once bitten, twice shy.)
I'm more asking about whether it is appropriate to ask for help building the puzzle, either here, or on PSE.
If I'm told it is not, I'll be quite content to abandon the idea, at least, as far as stack exchange is concerned.
(I would have thought asking would get an up vote, , or be ignored, rather than being "spat upon," even if it's a type of thing people wouldn't want to see, as it is an attempt to not cause problems.)
Anyway . . . comments on the StamPuzzle concept, or the building of individual puzzles, would be welcomed.
