nicename does not need to be kept private (though some folks like obfuscation)… but the nicename limiits what you can have for a display name… for example, I could not be Mr Papa but would have to be mr-papa…
If you like, there is no reason why you couldnt also display the nicename in the user info area… a pretty simple addition… in your functions.php file, add this:
add_filter(‘sph_user_class_meta’, ‘my_user_info’);
function my_user_info($list) {
$list[‘user_nicename’] = ‘name’;
return $list;
}
then where you want to display the nicename in spTopicView.php, just add:
echo $spThisPostUser->user_nicename;
you may want to style it…
and as mentioned, we are continuing to discuss potential methods to try to use display name… its just going to have to wait for 5.3 release and some mobile theme activity…
