Another MT/IA post, but this one will be a little different.
If you look at the rules closely enough, there are certain areas that are rather broad in some respects. Some areas specifically list different possibilities. I think this is intentional in the game. D&D is meant to be flexible so that anyone can play it in whatever way they want.
However, one thing I find ironic is that over at the WotC boards, they have forums specifically designed for asking questions regarding what is "by the rules." Yet, if the game is so flexible that there are areas in which the DM has to decide which way he'll go, why have a discussion on which way is "right" or "wrong" when it's supposed to be any way is "right" or "wrong?" I've taken part in my good share of rules discussions, and it usually seems to end up that there are different ways to do it, and different people will stick by their way no matter what others tell them. My question is what the heck is the point of these forums about the rules? The chances are that any rules question is due to a gray area in the rules, unless the person asking the question is new to the game and doesn't understand it. In that case, there are discussions in which veterans help out the new Players, and by experience, the people will figure out if they're doing something the wrong way. If they don't, then it doesn't even matter, really, if they're enjoying the game.
