Remember that just because there is a time listed next to your name, that doesn't mean you have to wait until that time to make your pick... As long as everybody before you has picked, you can pick ahead of time. The times are listed in case we have another 4-5 hour dead-zone with no picks. Of course, the 6-hour rule will also.
Also, it's not a bad idea to check back shortly after posting your pick - in case it's an illegal pick. We don't want a long delay waiting for a re-pick, because you assume you don't have to check in for another 12-24 hours.
Thanks
