I just got this e-mail from The Netflix Prize:

After discussion among the judges we have decided to reduce the time between prediction submissions from one week to one day. This change will go into effect this Thursday, Oct 19, 2006, 16:00:00 UTC. A new copy of the Rules and the main FAQ will be posted at that time, reflecting this change, a clarification on the constitution of teams, and other helpful suggestions from many of you. We'll be updating the Forum FAQ entries to match soon after the change.

This is HUGE...you know assuming I ever the time to actually make an entry.
