Alright, I know it has been said already by Brad, but the sub forums are up and running. Although starting out small for now, each Category can potentially have X-amount of "Sub-Topics" to post under.

So, take for instance Politics.

When you are posting you will see two drop down menus. If you have selected the Politics Category, then the page will refresh with a second drop down menu displaying the following options:

Topic:
[General Discussion]
Politics->Democrat
Politics->Democrat->Dean
Politics->International
Politics->Republican
Politics->Republican->Bush

Choose any Sub Topic you wish to post under.
And there you have it. Two easy steps to posting an article specific to the topic you want.
