How do we display 2 badges for a user like this forum does? Some "staff" users have 2 badges here.

And I'll add my voice to the many people who have requested automatically displaying badges instead of users having to dig into their settings for it.

More necromancy. This probably isn't the most elegant way to do this, but it seems to work, and the other two posted above no longer do.

<script>
try {
  if (!app.user.uid && window.location.pathname
    !== '/login' && window.location.pathname
    !== '/register' && !window.location.pathname.startsWith('/reset')) {
    document.location.replace('/login');
  }
} catch (error) {
  // the page hasn't yet loaded
}
window.onload = function () {
  if (!app.user.uid && window.location.pathname
    !== '/login' && window.location.pathname
    !== '/register' && !window.location.pathname.startsWith('/reset')) {
    document.location.replace('/login');
  }
};
</script>

For future reference, this is what you have to do now:

<url>/admin/manage/privileges/
Change "Configuring privileges for..." from "Global" to each category. You can then remove all "Guest" privileges.
