Poor skript (no else: and also looping all players), it's so easy to make (too simple), don't post random junk that has been posted thousands of times, you could instead remove the [] around [<text>] and add a usage to show the same error message, etc. etc.
I can post whatever I want to on here even if its been made more than once it doesn't matter every single skript is different. Have people posted this exact skript more than once No because its different.
