Quick Stats is a tool that's located in the Admin Dashboard that displays the number of views, edits, and photos uploaded to the wiki for the day.
QuickStats is located in the Admin Dashboard on all wikis you have founded or are an admin (sysop) on. It can be found by clicking on 'Admin' in the universal Toolbar at the bottom of your screen.
Once you are Admin Dashboard, you will see Quick Stats on the right side of the page. You are able to view more stats by clicking on the text that says "see more stats" which will take you to the more in-depth Wikia Stats.
