There is game that has been active now for over two years. It goes like this:
When a newbie (non smoker with less than a year of smobriety) posts, they add +2 to the number...
When an Elder (non smoker with more than a year of smobriety) posts they add -1 to the number
When either +20 or -20 is reached then that team wins the round...
Here is a link: Race to +/-20
Hope to see you there!
