I was thinking of setting up shop somewhere on the outskirts of the actual town, in one of the unoccupied farmer's houses, far away from hurty-owie mobs so people who aren't high level could come if they so choose. It'd be a great way to meet other farmers and perhaps get some mats that you need, whether it be fish, fowl, red meat or veggies. Have too many turnips? Trade them with another farmer for some reef octopus! Haggle!
Anyways, would anyone else be interested in something like this or is this already been done already?
