Hello, can somebody create a plugin what can write to a mySQL database to have it like poll? /vote 1 -> it will write 1 to a database /vote 2 it will write 2 etc.. and every player can only once. 

Hello, I could build this. Do you have a database made yet? Does it really have to be a mySQL database or can it save ingame the pulls to? Do you have to see it visual?

Should only save it to the mySQL database. Nothing else. Only write a message to the user in chat like your vote was saved. And can be only once per steamid.
