Part of my job, one of the more objectionable parts, is reviewing software documentation, user's manuals, etc. We routinely gig the writers for not including the definitions of all acronyms and other non standard abbreviations. We generally require an acronym list, but acronym is defined upon first use, that is OK as well. I actually prefer that myself. Doing both is better yet, in case one forgets what an acronym defined on page 4 means when you encounter it again on page 403, one can turn to the acronym list rather than searching for the first use.
Maybe they meant IUD
ARRG!
, but if acronyms are defined upon first use...
I'm a very poor proof reader. I'm generally the one who reviews for technical content, not spelling, grammar and format. :)
