This isn't to hard and this is what I did:
1. Create a new plugin via the plugin manager.
2. product - vbulletin
3. Hook - postbit_display_start
4. title - extra profile fields
5. execution order - mine is set at 5.
6. plugin php code:
Code:
if($post[fieldx]) $html .= '<dt>Name</dt> <dd>'.$post[fieldX].'</dd>';
if($post[fieldx]) $html .= '<dt>Name</dt> <dd>'.$post[fieldX].'</dd>';
$html .='<br /><br />';
$template_hook['postbit_userinfo_right_after_posts'] .= $html;
Edit all the red and as you can see you can add more to it copying and pasting the one line of code to have 3,4,5,6, etc.... You do need to edit the red so you will need to make the profile fields first then add this plugin.
