My username is lo2e on your site also, if you could give the extra 3 points. Thanks.
How is the list of cities organized? I could find absolutely no recognizable pattern to the list of cities. There are also a few wrong spellings in that list.
I would agree that it's very user unfriendly right now. If you have the technology to have a "database" of the lowest possible winning bid, that same "database" should be able to tell you how many zones are available in a particular city and which star levels are available in that zone. Or at least your "expert" should be able to get this information and program the site.
And I'm sorry, but why would anyone want to pay for additional "points" when there are other resources that can find out the same/similar information for free?
