I have a complete tournament set up and ready to go with four sub categories created for the different age brackets. But each sub category (8U, 10U, 12U, etc) is "Unlisted" and they are empty, nothing shows on the home page when you look at it in "Visitor View".
Actually, you should use the custom settings to make sure it is "unlisted" until you get it completely ready for the public to see.
For instance, lets just say you goofed when setting up your prices and then the gallery shows up for the public to see and the prices are the default price and not your custom ones which you forgot or overlooked. That could make for some uneasy moments until you figure out what the heck is going on. In the mean time eager customers are waiting to view the pics... OH MY, they are on sale! 
Good luck.
