I second that option ... I love the fact that you will be the first pool [that I know of] to offer payouts by time

I see more responses since this post and I am sure it is answered below.  Great job on the pool!  I love it!  Only catch is that my stale share rate jumped from about 0.2% to 0.9% [still better than I have been seeing with any other pool lately ... I think it is related in part to the time of day to some degree.  You pool has grown very quickly and it has handled it like a champ .. great work!
