title: Multiple relationships to the same models
body: <p>I'm having trouble figuring out the best way to do this. I have a User model and a Tournament model and I set up a has_many :through relation between these two models called 'followed_tournaments' so that users can follow a tournament. As such, I already have a has_many :tournaments in the User model and a has_many :users in the Tournament model so that a tournament has many followers and a user can follow many tournaments.</p>
  
  <p>I'd like to set up another habtm or has_many :through relationship so that a User can be considered a "contributor" to a Tournament -- a completely separate relationship than what I already set up. I'd like a tournament to have any number of contributors and the user to contribute to many tournaments. </p>
  
  <p>What's the best way to go about implementing this?</p>
