Is it just coincidence that another chap from down-under was looking for a squadron, or is this post at RoF forum yours?http://riseofflight.com/Forum/viewtopic.php?f=349&t=44276
Just from my experience, the fellows from your edge of the world seldom fly when the rest of us are active. I get up at ungodly early hours before the sun rises and in the past on weekends used to fly occasionally on Oceanic server (when it was up) and met those fellows in the air. Just as my day was barely starting in Eastern Standard Timezone of N.America, theirs was ending.
Other than Vintage Missions (when I basically schedule all of Sunday afternoon to fly) I seldom see the rest of my squad, who are mostly Europeans. For me VM's usually start around noon to 1 PM, or around 18:00 GMT. That's 4:00 AM your time I think.
Not trying to dissuade you from joining, because it would be great for geographic diversity, but timezones definitely must be considered.
