To keep combat running quickly, I will make all the rolls. Players will post with basic instructions, attack, retreat, missile fire, etc. and I will fill in the specifics and report. If a point during combat requires a pause to clarify a PC's action, we will do that. Otherwise, I will play out each characters actions and write a post summarizing the event. Having all of the players play this out round by round can make the game cool off really quickly. I will try to pace it accordingly and jump ahead if I think we need to do that.
Another thing I don't want to do is upload a ton of maps...dungeon or area maps. I'm going to try to keep it simple and describe it mainly in words. I will throw in some pictures to fuel the imagination and also a map here and there. But mostly I'd like to try theater of the mind.
Questions and suggestions are much appreciated. I want this to be a fun experience for all of us.
