Well, it has to be published to the site still. That entails it being sent to the Editors, then the Editors edit it, if it needs corrections it may be sent back to you, or simply corrected and published. It sounds like you might enjoy participating in the Mentor Program here too - a mentor is an experienced reviewer who will help you write good reviews and just navigate the site more easily. They can answer any question you have!
To join the mentor program to your "Account". Once there, on the left hand side of the page you will see your "Dashboard". (That's basically a list of a bunch of different stuff you can do or explore.) About half way down that list you will find "Mentor Program". Click on it, and then under "My Student Program" you can explore the Mentor List. Hope this helps!
