Here is a related issue, even if not entirely responsive to your message. Look at my userid to the left of my message. See the country flag ? if you hold your mouse pointer over the top of the flag you will also see my City. That is because I have provided this information in my Profile area.
Right now I do not see any of this information with your userid because it has not been entered.
Are you suggesting that I should try to do that with sellers to learn where they live? I do not think that is the best solution. First, many users do not fill out that information. And second, it takes a lot of clicks from the geek market to reach the user profile.
Either way, thanks for pointing it out. I did not know about that feature, and while cumbersome, it is indeed a way to guess the location of the item in certain cases.
