Like when BC Players are in game, they have the BC helmet next to them and when a ROBLOX Admin enters the game they have the ROBLOX R. How can I change this to the picture to the group's logo? And how do I make one division higher then the other, so the highest one is shown if you're in more than one.
What you are asking for is a custom Player Leaderboard.
I know it is possible because lilly (imnotaguestimagirl) did it for her group, Vortex Security places. But i think you have to go through the player and membership type maybe?
I do not know. Just have a browse here: http://wiki.roblox.com/index.php?title=Player
Best of luck!
