Basically each post counts as 1 number
So you can only post your number once, then you must wait for someone else to post the next number e.g.
User 1: Number One!
User 2: Number two!
Admin: Reset!
User1: Number One!
And so on... If you get to 20 you win the game, its common sense really.. but anyways have fun!
i shall start!
Number one!
