wait ! Why add with your mod features? I has my own plan ideas features for player list.
Why would I add extra features?
Because quite frankly you seem to be incapable of creating a functioning script.
Don't get too offended, it's just the truth, and as such, I will create your add-on for you because you requested it, but I might just add in some other features. Like the possibility of the server to display other variables alongside the "score" variable on the player's list, for example.
