If you don't want Georgia, you would list in the National Classifieds, or I am not following you?
And the specific location box can have just the city name put into it, doesn't have to be a zip code.
You didn't follow me, some users put their location as GEORGIA, GA is a big state, just putting the State as your location keeps me from making offers. If a seller or trader doesn't care to list his City then his listing gets ignored.
This has nothing to do with National Postings
