Common sense says when the rules don't make sense or they don't do what their supposed to do you change the rules.
Therefore - NEW RULE: As always a thread can be started as soon as 24 hours before gametime. However, if you started the last thread you can only start a thread 23 hours and 45 minutes before gametime. You may start as many threads in a row as possible if no one is starting a thread.
The 15 minute window is more than enough time for someone to get in before the last thread starter and take the best player available. In the case of my multiple threads, I started them about an hour and a half after the 24 hour window, not just 15 minutes. But still no one started the thread and I am not waiting all night for someone to do so. I am not waking up early to sign on to hfboards the next morning before I leave for work just because no one started the thread.
This will also solve the problem of people whining that they aren't winning because they didn't start as amny threads. They will have an advantage now to get a pick in before the last thread starter. If we have to amend this rule to make it the next 2 games after a thread was started then we can do that.
