How do i make the display name default the username?  SMF was set up originally to display the username as the deafult setting.  The new bridge makes the users real first and last name the display name.  Any suggestions on how to change it?

it would be great, if there was an easier way to do it.  I know that a good amount of people will not like the way that the forum displays their real name as the default setting.

thanks!  The old versions of the bridge use to have this feature so I am sure that other will really appreciate it too.
