Re: Filter Wiki pages by User
In regards to show "pages that have been created by a certain user(s)", Wiki List Pages can show you the page creator and Last editor. To show those columns in the list pages report, go to Admin home, Wiki, Page Listings tab and select "Creator" and "Last modified by". Then go to Wiki, List Pages.
And there is a way to list all the things a particular user has contributed to.
First go to Admin home, Community, General Settings tab, and select "Show user's contribution on the user information page", and Change preferences.
Once that is set, go to Admin, Users. On the "Admin Users" page, at the right of the user's row there is an 
icon for User Information. Click on that Icon, and then, on the "User Information" page that comes up, click on the "User Contribution" tab.
