Display user name possible?

I use EBR as a comment bulletin board for my website. Only registered users may enter the area where a new GBR entry can be initiated. Currently the EBR entry form auto-populates the full name into the entry form (rather than the user name the person uses to log in). Is it possible to modify EBR to enter (auto-populate) the "User Name" instead of the full name of the registered person.
Thank you
