Creating a Group Ranking system from in Studio?

Hello!

I’ve been searching online for a bit and found some Community tutorials from the dev forum as well as some tutorials on youtube. Unfortunately, they all seem to be outdated or use a website called glitch.com which does not work for what I’m trying to do.

What I’m looking for is a system to set the ranks of users in my group via studio. An example would be from the Roblox groups IHOP’s Application Center. They have a game that allows you to complete a quiz for a rank in their group!

I have no idea how to implement this in my own group… thanks for any help in advance!
