What do you mean find it?
I think there have been two hosted total for the writers, three counting the ongoing one. For the most part, if you make a tournament thread, it will be found, but you'll need things to make it work.
Respect.
Drive.
Something to make it interesting.
And possibly a positive reputation, but diffidently a lack of a negative one.
Things your target will need to join:
Time.
Trust (of it's success).
Interest.
Personally, if you're looking to make one, I'd recommend building up a reputation and planning it out. Hewitt's got a tourney going on right now so if you're making a writing one, most of us are occupied with it giving us a severe lack of time. It'd probably be passed up on through no fault of your own at this point, so I'd advice holding off until it's been over for a while.
