Law governs you as such in a descending order: Constitutional Law -> Federal Statutes -> Federal Regulatory Law -> State Statutes -> State Regulatory Law -> Municipal/Local Law. There are others, but those are the biggies. You must follow all law that applies to where you live, the US, the state, and the municipality. There are some vague areas that apply to things like forums that are internationally held (such as online gambling and such), but this one's based out of the US so it could, in theory, be in jurisdiction of either the place of the server or your own residence.
Granted there are probably no major laws that differentiate the 2.
But what local laws are you talking about? It sounds like your are talking about contracts (legally binding), which isn't local law but K law.
