Many of our members are new, and don't realize just how world wide this forum is.
It took me a while to truly understand the enormity of the concept. We're used to dealing more locally.
Listing location is totally voluntary, and many would prefer to keep their anonymity.
Its equally frustrating to deal with problems that people ask for help with when you don't know where they are located. Location is important because availability of books, prices, shipping, etc varies so much around the world.
Shoot. It took me ages to figure out where "oz" was. I finally had to ask.
So be patient with us. Its not that big of a thing, when you realize no one is doing it to be deliberately obtuse....a simple request for location will undoubtedly bring results...
