We have now made it a User Option whether to display your First Name and Last Name on your Forum Profile Page.
If you go to your Profile Page and click on the Forum Profile Tab, there should be a checkbox that says "Show my full name on the forum member profile page".
If that box is checked other registered users will be able to see your full name. By default, that box will not be checked.
As far as showing your Occupation and Location in your Profile, that is optional. If you leave that those fields blank it will not show up in your Profile.
