Multiple people issuing commands to the bot, all at the same time, is something I've been thinking about. Since this particular snippet is just one of many possible commands, I didn't embed trigger flood protection here specifically. It is my hope I'll be able to work out a better solution at a higher level. But I do appreciate it being mentioned :) keep me honest guys ;D

@SReject: I actually did start off with something similar .. not nearly as elegant as what you posted here, but along the same lines. I ended up expanding it mostly because of people wanting to see individual rolls, and to identify natural 20's
