I'm fairly certain Jason is aware of when the lineup locks. His questions/complaint is that the time-reminder indicated 4 hours, but it seems like the reminder rounded up the BB game start time and did not give him an accurate time of when the game would be beginning. Most games will start on the hour, while BBM games sometimes have weird start times and the notification reminder may not be precise enough.
Yeah normally I pay attention and I'm on top of my schedule.... But on the rare times where I'm busy and forget it's always nice when that 4-hour email comes in and reminds me.... So I saw that in the morning and thought when I logged on 24 minutes before 10:00. I would have 9 minutes to get my lineup set.... But instead learned that my game was starting in just a few minutes..
