In my company, we use GitLab and the user name is different from the name one commits with. This is due to our LDAP connection, which gives you a username like JDO for John Doe. Now I can't look at the person's face when viewing ones commits if they got registered after the LDAP connection.. :(

But the positive thing is that you can search a user's info by email. :)

Btw, I loved what you did with the WYSIWYG settings editor.
