Just wanted to offer some insight on the potential of posting multiple rounds:
The only issue I see is that if you know which team you are drafting from next round, it could help you this round. For example, if your current franchise has a good SS available, but you know your next franchise also offers you a great SS option, it affords you the ability to pass on the SS with your current franchise and pick someone else. If we want to avoid that, we should post only one round per day.
However, if that's not an issue for people then theoretically we could just post ALL rounds at once, and then people can simply post as soon as the person before them is done for each particular franchise.
So either one round per day or post all rounds at once should work. There doesn't really need to be a "half way" option of posting several rounds at once, IMO.
