Enter user group banners:
Banners can be configured per user group:
(I am aware of the first banner on the second column having its top border wrapped back. This is a browser issue that we're looking into.)
You'll note that this set up is similar to how thread prefixes are configured. You can use custom CSS classes to completely change the display of banners (such as by replacing them with images).
I've demonstrated that you can have more than one banner displaying simultaneously. By default, they'll be displayed in the display style group order (highest first). If the user is a staff member, that banner will take priority.
You can disable this option and configure a few different options (globally):
You'll also note that you have the option to override standard user titles with banners.
These banners are primarily displayed on messages, but they're also shown on profiles. There is a simple template helper function that can be used to display them anywhere.
