Show Real Names on Forum

[David Karol]

We recently converted in FUDforum. We have always required "Real Names" in order to post in the forum. Here, there is no field for an Alias to display throughout the site.

Searching through the forums, I found multiple posts on having a custom profile field's entry display above each specific post. Is there a way to replace any display of a username throughout the entire site with that custom profile field's entry? (Display Name or Real Name)

Thanks
