Ask Michelle. The way this works is no matter how far ahead you get unless you finish you are at risk of hitting your 72 hour limit if you don't post within 72 hours of your last post. THe time resets everytime you post. However if you let Michelle know that you have a situation where you will be unable to access a computer for a few days and that you have done the work ahead of time, she will usually keep it from rolling over on you.
