The individual For Trade threads are kind of an organic outgrowth to trade within their individual communities....look at them as a "Farmers Market" that's barter based. Clyde's is fairly specialized in nature as well, for an example and came about to make the heavy duty needs of the Clydes more easily findable. It's not really all that active, either...but needs to stay where it is, basically.
