Listen, players. I know it is in a player's nature to be cavalier where it comes to answers and giving information . . . we wouldn't be D&D players if we didn't have a strong sense of individuality and a need to express same in a variety of ways. I'm knocking you square pegs into a round hole and you're bound to feel ill-used. I get that.
But if I'm running this many players, getting you all started, getting this thing off the ground in the shortest possible time, then Short, Precise answers are practical. The more lackadaisical you are, the greater the chance that I'll miss something or misunderstand something. We're operating in print, right? It takes time whenever I have to comment to clarify something and you need to then clarify it, time that we don't need to take if you'll just be Short and Precise the first time around.
At least in the beginning, just do it by the book. It will be good practice for when we get into combat, which is a trial to manage in text and with pictures. Don't feel ill-used; just accept that communication and clarity is more important than individuality right now.
I mentioned Van Halen and M&M's in a comment a few minutes ago.
