I generally dislike using caps for shouting, or anything for that matter, when I write. Since it isn't actually a script we're writing, but a story. And you don't see J.R.R Tolkien writing "ELENDIL!!!!" in his books, whenever Aragorn swings his sword and kills 50 orcs with one blow.

Not to compare any of us to that old fart though, new generation and new rules - all that jazz. I just prefer to avoid it myself, ifat all possible.
BUT THAT'S JUST HOW I WRITE, HURRP-A-DURRP! 8D
