I'm certain there's a reference list somewhere, but I haven't been able to find it. Can someone tell me the difference between "difficult" and "tough" in the quiz ratings? And/or where to find the reference list?

I think you could probably find several threads about this in the Ask the Quiz Editors forum.

The order of ranking for difficulty is here:

Thank you, gtho4.

(Now to find out how to delete the post I put in the wrong forum.)

OK, this is weird. Just after I read gtho4's answer I discover there are other categories, too!

1. How does "hard" fit in?
2. Are there other words coming to the reference list, either present or future?

Don't worry about deleting any posts, your post was moved to the correct forum.

And yes, there seem to be two different sets of difficulty ratings, depending on what quiz list you're looking at.

Also we prefer that people do not delete posts which have already been answered, nor to edit them other than to correct a typing error. If you add anything to a post you can say 'edited to add...'.

If posts are deleted or drastically edited once a reply has been made it makes an absolute nonsense of the reply/ies and is irritating for anyone trying to read the thread.
