Modification Hide First and Last Name to Only Display Username

It is very common that, in an effort to protect privacy, an administrator will want users only to be displayed by usernames.
In order to change SE4 default showing first and second names, do follow:

1. Log into your admin panel and step into a "Profile Questions" page under the "Settings" tab.

2. Delete the "First Name" and "Last Name" profile questions.

3. Re-create both fields, ensuring the profile type is set to Single-line Text Input (NOT "First Name" and "Last Name"). If you don't want these field to be visible on the users profile, be sure to select "Hide on Member Profiles".

4. If you already have existing users, you will need to run the following queries in your MySQL database to clear their display name:

Code:

UPDATE engine4_users SET displayname=username;
