Only the big boss can create a tournament within a fellowship. Anyone with a membership rook or higher can create their own public tournament - simply go to the "Tournaments" page (found on either left or top links, depending if you're using row or column layout), and there should be a link towards the top of the page that says "Define new tournament". From there, you can set up things like the game-type(s), description, time limit, membership levels, section size, start date, etc.
