I see the treasury as being in a more static place than a forum, perhaps what Drupal calls a Page or a Book? This forum is like none I have ever seen, it doesn't act like the thousands of other forums I have seen. I'm not sure how to interact within it. There is a hierarchical list of them here and you can see that the top level (called a category) 'holds' the forums. I created a brewing Forum in the non-members only section. The Members only section has events and meetings forums. There can be any kind of post inside any of the forums.

Hard to believe but supposedly this site's forum is running under Drupal also. I am a bit overwhelmed here having only started to look at Drupal with this project really. In fact there is a whole discussion on Drupal about the issue of the forum's look. There might be a project called DruBB ready next year that will make it easier to style the forum more like a regular forum. In the meantime, I think we need to continue to play with the system as is and see if we can work in it.
