Is that what the mod interface looks like?
Interesting stats in the screenshot - Don't see the red "banned" text when I click the user.
Nah, it's not mod interface.
Nutildah is using
Bpip.org extension that's why his interface is like that, if you want yours to look like that all you have to do is install the extension.
