Personaly, since I'm on the west coast, an hour earlier would be great. It is Friday night after all, and I can gt out a wee bit sooner.
The established time is fine by me, and I totaly agree with what APDrone said about cultivating the FSO over the years to the number of players we have flying currently, and how a time shift might disrupt the hard work, up to this point, to enlist this many pilots to participate in the events. However, there would be no harm in running a poll so that the community can give you it's honest input on the matter, not just the people who read and or post on the boards. Just a thought.
