I am new to scratch, and I see a lot of projects use cloud data for leaderboards. I want to make a leaderboard for my game (https://scratch.mit.edu/projects/1332113542/ )but don’t know how to get or use cloud data to make a leaderboard. Any help is appreciated.

I don't know too much about cloud data unfortunately–but you'll have a better shot at asking this on QaS (Questions about Scratch) or HwS (Help with Scripts).

Cloud Variables are earned by promoting to scratcher (but currently, there is a bug that blocks random scratchers in all ranks from using the variables but can read the data monitor).

You have to be a scratcher. (get on to your profile, click the purple letters next to "New Scratcher" do what it says then you're done!)

also, when you scroll down on discussion forums click "Change Signature."
