A view where a user doesn't have a certain content type I am trying to create a view where a user doest have a certain content type.

Say for instance I have content types A, B and C and I only want to return results to show users who don’t have content type A but could have B or C. 

I have created a view for (users) and linked it to the content authored. I have played about a bit but haven’t managed to find the correct filters. Can anyone help??

Many thanks 

David
I am pretty sure what you need to do is set in the access permissions of the view to be permission: Publish Content
