There are a number of fields available for version history tracking on Knowledge Articles, but I am not seeing where we can include who last published an article.
When you look at the Version History for a particular article, you can see publisher info such as "User A published article on Jan 5, 2014 at 7:45 PM"...this info doesn't seem to be available anywhere else.
However, I found the following article that says it should be possible to see the Last Published By info: https://success.salesforce.com/ideaView?id=08730000000hE5oAAE If it is something that has been delivered, then where can I see this?
