I have a brand new vBulletin forum that will require you to populate mySQL database with world cities. There are about 4 million cities around the world. You'll modify the .SQL file I will provide to you to include the cities and upload it using Linux shell prompt.
In your bid, please let me know if already have the database of cities around the world and how many of them. It's OK too if you don't have those cities, I'll buy it myself.
