From what I'm reading, you can only choose US East or US West when you create your account. Which means you need to start over and choose US East in order to play with us.
Once you're in if you click on the "Join" button, just type in the game name and password. You don't need to find it in the list.
If you click on Create, you should only be able to put in a game name, password, and a few options on how many skill level difference is allowed, how many users are allowed, etc.
