I have a view where I'm showing all postings by post author. Right now, I show (and filter) the posts by author name using contextual filters.
I want to change it so that I still use the username in the contextual filter, but when I override the the title, I want to show the human readable name.
So, for example,
www.example.com/postings/kyle.keiper
Currently shows
Postings by kyle.keiper
in the title.
How can I change the view so that the URL stays the same, but it shows "Postings by Kyle Keiper"?
