Hi Daniel Bachhuber,
I am using WordPress version 3.8 with theme "iTheme2". It is very much understandable that admins have power of adding co-author with your plugin Co-Author Plus. But i want every author in my website to add their own co-authors(yes all the authors know each other and wat to work as a good team) for their articles. How do we solve this problem? As far as assigning role is concerned, here is the screenshot for Author role management - http://oi44.tinypic.com/21329lv.jpg
Second problem: It is not showing up in the post preview or published. As an admin when i add co-authors(search as you type is perfect and the display box is fine) then the published or previewed post should show co-authors. I dont think it matters or not whether i use Fancier Author Box or not because i have tried disabling this plugin as well. I am sorry i dont even know where actually does the co-authors show up when i preview or publish the post so i am very much frustrated right now, i cant change theme and i dont want to delete co-author plus plugin.
Your help is needed Daniel.
