I'm not sure if this would appeal to anyone else, but I'd like it if dealers/FFLs had some sort of separate icon or distinguishing color in the Title of their post, so that I would know if I the item is being sold by an individual or an FFL. Sort of like how on Craig's List in the car ads, they distinguish between dealers and private sellers. Also, it might be a good thing if there were a limit to the number of guns a dealer can list at any given time.
