I have it installed and looked around your support blog for the answer but have not found it for this.
How do I assign a writer to an article/post? I found the photographer box.
I have made sure I have users in the "Reporter" user group.
The only other place I have been able to assign the author is in the Quick Edit box when looking at all posts.
Also- I only have a couple of photographers in the Photographers users group. Many more folks than that come up in the drop down menu for Photographer in the edit a post menu.
Thanks for your help.
