Two areas you might want to consider adding. A new geographic section for the Ozarks might be nice. Most people would put it in the Midwest, but some, especially in Arkansas would rather be put in the South, but since it is unique environment from may perspectives, perhaps it should be on its own.
The second one is a sections dedicated to teaching PC. I'm about to start teaching a PDC for the first time and it would be nice to be able to talk to others who are teaching or are interested in teaching without spreading things over other boards.
