Best thing I can say is to be a shining example. Leaders aren't just the people hand-picked for the position, they're the people who rise to the task. You don't have to be a Bungie employee to have an influence of the community, you don't have to be a ninja to help others. All of these things can be done simply by making good, well thought out posts, putting up helpful replies, and continuing the conversation in a manner pleasing to all. Don't wait for a leader to be picked, be the leader yourself.
