Gingerbread Man: my intent in keeping these turns confined to single threads is to encourage discussion on all topics. There are no instructions per say, but it is a leader'd duty to help make decisions, not to have the decisions to yourself. Post polls, start discussions, etc. That way, we can make decisions through general concensus, rather than direct order.
Generally, I take into accuont whatever active discussion or polling that has been going on. GBM, just keep on talking, and making suggestions.
