Didn't we already cover all of this here:

How do I create a list of tags in firebase?

Hello, I want do send the data to the fire base with the tag User and a number, if there is already a "User1" then it would change the number by 1 so that another user's tag would be "User2". Does anybody know how to do this? I was testing it with join function but I really can't think of anything, I tried to make a list in the fire base but can't understand how it works. [image]
