As a New Zealander, the PGP list is unfriendly because there are plenty of words that are hard to spell, or are too US centric.
dogsled (contains silent d, and sleigh might be a British spelling)
Galveston (I've never heard of the place)
Geiger (easy to type i before e - unobvious)
Wichita (I would have guessed the spelling began with which or witch)
And why did the designers not make the words have some connection to the numbers e.g. there are 12 even and 12 odd words beginning with E - add 16 more E words and you could use E words for E0 to EF. Redundant encoding like that helps humans (and would help when scanning for errors or matches too)
I imagine it is even harder for ESOL people from other countries! I am sure the UI has completion to help - but I wouldn't recommend using that list for anything except a pure US audience.
