I am not sure about specifics but having run several over the years I have found that they can be much more work than you would reasonably expect & players wander off quite commonly I had one leave because he was knocked out in the first combat and had to wait three turns (days) for the healer to revive him he could post 5-6 times a day & expected every one else to the healer could manage the required one a day.
Typing which reminds me I was in Hard rains game and if I recall correctly both the other players drooped out and she sort of gave up as it was getting busy at work. I will have to chase her up as we dont Chat on line any where near as often as we used too.
