Setting up a Dropbox account
One way to test your game early to see how it performs in a real environment is uploading it to a Dropbox account. You preview the game on your computer, but it isn't the same as uploading it to a website. The reason is that the resources on your computer are much greater than the resources on the server.
If you do not already have one, you can get a free account at www.dropbox.com.
Once you have a Dropbox account, you can export the game.
