So now I will jump on your bandwagon. Other examples of areas that could be combined: Seattle and Portland are both pretty lifeless boards. They could possibly be combined into a Northwest board, then add in Idaho and maybe Montana (both who don't have boards) Kansas and Missouri could be combined. Kansas board is dead and Missouri is a heartbeat away from death. I think the idea might help some existing areas as well as serve some of the areas now covered under "other cities."
Unfortunately for my home area of Hawaii, i don't think there is enough activity to support it's own board, but it would also be hard to combine it within a region, as there are no close regions.
