I doubt there’s a plugin for it. But you could just go into the user-edit.php file and edit it out.
Look for this:
<p><label><?php _e('Nickname:') ?><br />
<input type="text" name="nickname" value="<?php echo $profileuser->nickname ?>" /></label></p>
And change it to disable or remove it.
Otto42, thanks for that.
Instead of disabling/deleting, how to make sure that nicknames are unique? (so a user does’nt steal a nickname of the blog admin, for example).
Whooami, the links in the code you quoted don’t work because he’s no longer supporting his WP plugins.
But you can get the original PHP file for Impostercide here:
