As administrators, William and I can post 'announcements.' An announcement will be the first thread on every one of the boards. This would be used when there is an imperative message to get accross to everyone.
We can also 'sticky' threads. Usually, topics are ordered by the last post made on them, with most current first. By making them stick, we can keep the topic at the top of the board. I have done this to FAQ threads. We may also use it on important threads like details for the Reunion, so that even if we aren't discussing it right at the moment, it doesn't get lost in discussions.
Hot topics will receive a icon. These are topics that have at least 10 posts. They are distinguished to bring attention to them.
Very hot topics will receive a . These are only topics with 20 or more posts.
