Admin icon on scoreboard

[BasedRebel]

So this is probably really simple, but I would like to add the "wand" icon you see next to the super admin and admin usergroups when you press tab to other user groups aswell. I have a group called "admin-donator" that I want to be displayed as admin in the scoreboard. The gamemode is murder, if that even matters. Thanks!

You're question isn't exactly a Ulysses project "how do I/help" question, but for now, I'll leave as is.
I presume that whatever the scoreboard uses is Gmod's IsAdmin or IsSuperAdmin check.
Therefore, to get it to work without any code modification or making your own scoreboard (far beyond what this area of the forum is for), you'd need to have admin-donator inherit admin group.
Honestly though, superadmin and admin groups are top and 2nd most highest groups in Gmod. You may not want to do that.
