It’s a way to make the NICKS of the Admins have a different color (yellow, red) from the other usual members?.

And a way to make the ACTIVITY post’s glitter in light yellow or something if they are new from the last time you logged in?

you could change up the logic to include the site admin or other various roles/caps
