I've never understood why the New Orleans board doesn't include Louisiana. Yes, in a strictly geographic sense it fits into the South. From a culinary perspective, the regional cuisine of Louisiana is distinct from the South.
I suspect that most out of town chowseekers don't understand the difference between Creole and Cajun. The many tourists who post on the New Orleans board would be well served by also seeing info about Cajun country, which is often a frequent day trip for visitors.
