I'm totally with yomiko above. It's like I blink and there's either a new round or the round is over WAY too quickly. >.< I've never written more than ONE fic per round! I'd write more but I just never have enough time or I'm completely missing the rounds! D=
I feel five days to a week for getting in prompts and two to three weeks for writing are respectable. So yeah, a month for a round, then a month off (or two, I'm not picky) would be great.
