If you want to make a new game and then make it anonymous go to the "New Game" tab on the top right corner of this screen. Click open advanced settings, and scroll down to Anonymous Settings, which has a check box to set all players as anonymous.
If you want to join an anonymous game go to "Games" on the upper right, and click the tab that says new. Underneath the pot size of each game is a line listing the games settings, anonymous, winner take all vs point per supply center, etc. I also advise you read over our rules and FAQ located here (http://www.webdiplomacy.net/rules.php) and here (http://www.webdiplomacy.net/rules.php).
