https://community.socialengine.com/forums/topic/2891/profile-name please see that feature request. You could do like I suggested in other thread for this same question. Change the first name profile question to Display name. Then make the last name field not required so that you can delete that. Once you delete that, make a profile question for "Name" or "First and Last Name" which the user can put their full name. It would only show on their profile info though. For now, that is all I can think of.
