So change it then... Here's How:
Select "Profile" then "Forum Profile"
Select "Modify Profile" then "Account Settings"
You'll see a page with your "Username" at the top (sorry, you can't change this) and a "Name" field where you can change the Name visible to all Forum users. You can change your name to whatever you'd like in this field.
Don't forget to save the changes...
