OK, got a couple of questions regarding passwords and the checker, as a recent password I worked out could easily be one of four very similar words.
Which leads to these two questions (examples made up in case anyone was wondering):
1) If there is a UK and a US spelling, would the checker only be programmed with the UK one? Or both? Or just whichever the clue setter decided was right?
Example - if the answer was "colourblind" it could also be "colorblind". Or, there are other words which can be spelt multiple ways, but mean the same, such as "griffin" and "gryphon".
Also, would the letters the pyramid holders have been carefully selected to avoid this kind of ambiguity?
2) If the word could be a plural, would the checker recognize either? And would the "s" be one of the letters?
Example - if the clue was "a group of these eat grass and make milk", the answer could very well be "cow" or "cows".

I ended up with a password which had both of those problems so had four potential spellings, which would have taken two weeks and £14 to check if I wasn't convinced the checker was intelligent enough to handle it.
