Contributor Names are showing as Usernames

Jul 4, 2012 at 4:31 PM

I am working on a blog with multiple contributors.  Each contributor has their own blog that is being aggregated into one.  For this application the Contributors widget is very useful for allowing people to filter just the blogs on one contributor.  The issue is that the Contributors Username is openly appearing as the Contributor name.  I would much prefer to see the contributors full name (First + Last Names). 

Is there an easy way to do this or do I need to modify source code?

If I need to modify source code what location in the code should I start?

Just a suggestion, it would be great to have the normal name combinations available to use in cases like these.  AuthorFirstName, AuthorLastName, AuthorFullName etc..
