The only acronyms used in a piece of writing should be ones commonly understood on their own. That is: FBI, CIA and the like. No others.
I don't care if the article mentions the IGRJTYAA (the International Great Regional Jam and Toast Youth Association of America) over and over and over again. Don't use the acronym. Call it the youth association on second reference. Call it just the association.
For God's sake, don't call it the IGRJTYAA.
Just because the story covers the group doesn't mean readers know the acronym, or that they will become accustomed to said acronym in a few paragraphs. Give them -- give everyone -- a break. Use real words.
