To send a PM, simply find the user that you want to send the message to and click on their name(next to their avatar) and it will drop a menu down. In this menu look for 'Send a private message to <insert username here>' Click this and it will take you to a message box where you must type a subject first and then the message in the message box. Click preview to see your message before it is posted and then if everything is ok, click on the post message button.
