While we are on the subject, I shortened your display name. There's no reason to go overboard.

If you don't have very many to edit, you can just go in their profile and change it - Like I did.

How to find all significantly changed names:

Code Select Expand

SELECT * FROM `smf_members` where REPLACE(member_name," ","_") != REPLACE(real_name," ","_")
List can be fixed with a help of phpmyadmin.

If you're already doing that why not just

UPDATE smf_members SET real_name = member_name;

and just be done with it?
