Thank you, Hyla, for picking up on something that has mildly irritated me for years.
Strictly speaking, I think and acronym should be a set of initials that spell a word already in the lexicon, but I am quite prepared to accept the term for pronounceable words - especailly if they then become accepted as words in their own right.

But a list of initials is a list of initials - not even really an abbreviation.
