Also remember that once your application is approved & you are a member of the forums (have the e badge below your name in forums), then change your (Steam) name to also include =(e)= in the beginning, so you do not get mistakenly kicked while playing on the server.
To change your name on Steam, click the "View Friends List" at the bottom-right of the screen when you're in the Library pane. This will pop up your friends list. Then click the little down-arrow next to your name at the top of this window. Then click "Change Profile Name". There, you can add the =(e)= tag before your name (just copy and paste it in there).
