How to display a custom profile field for $lastposter, $newuser?

[dannylin3000]

I'm creating a custom profile field "Nickname" and make it all displayed in every post but somehow I found out I was unable to display such custom field when displaying $lastposter, $newuser, Thread Starter or even in the 'newreply_reviewbit' template.

Does anyone know how to display a custom profile field for such condition?
