Welcome to the forum.
I don't know about that site/contest in particular...but there is something that you should be aware of.
Some sites have contests like this, with the promise of prises and publication in their book. What they actually do is tell everyone (or just about everyone) that they have made the next round etc. just to get you excited. They tell you that your photo was selected for publication and you can buy the book for only $89 (or something like that).
If you look into it, you will see that the book actually has thousands and thousands of tiny photos. They publish all the photos in order to suck people into buying the book at a hugely inflated price.
