Damn, you HAD to point out the "a" vs "an", but completely overlooked the "their" vs "there" vs "they're" gems in the other post above.....
Heh... I wasn't pointing out grammar of other peoples' posts... I was mostly commenting on my own struggles with "a" vs "an" when it comes to acronyms.... I'm with Sagath on this one... I can't use "a" when the acronym sounds like it starts with a vowel... it hurts my head to do so....
