You may have already received a response, but if not - you'll need to get into your User Control Panel and there are a couple ways of doing that. At the very tip top of the screen, you can click it (it's the third command at the top). Another way is by selecting the "Forum Actions" --> "Edit Profile" drop down menu right above this Visitor Messages tab. It's in the darker menu bar right above this message box's menu. Let me know if you need any more help!
