1 - We already have a very similar setup to the Belgium team from what I can gather having a quick read over that page. Our missing statement isn't long and large but from our main team page
"The Australian team focuses on distributing, advertising and demonstrating Ubuntu within Australia. Through the development of our projects we focus on the areas of schools, business and home users." is what I would consider our current mission statement. If it needs revising then lets have discussion on it on the mailing list and talk in the meetings.
