Ok, This is what was just handed to me form vbulletin.com, I haven't tried it yet so, will see....
You can keep using the username markup, but you will need to edit the templates for the areas where you don't want the markup to show. For example:
Admin CP -> Styles & Templates -> Style Manager -> ? ? -> Forum Home Templates -> forumhome_loggedinuser
Remove the
m that is highlighted:
Code:
$stylevar[dirmark]<a href="member.php?$session[sessionurl]u=$loggedin[userid]" rel="nofollow">$loggedin[musername]</a>$loggedin[invisiblemark]$loggedin[buddymark]
You will need to make a similar change to the other templates. You can find these templates in your:
Admin CP -> Styles & Templates -> Search in Templates
Search for "musername".
