"The Spreadsheet".  Has all the activities that need to be taken care of for a successful tournament.  Just make sure someone is assigned to every task and that things are done in time.

Outlines in detail every volunteer position called out in the spreadsheet.

A starting point for your tournament rules.  You can adjust them within reason, but make sure guests know about anything unusual.

Something you can use to reiterate to the parent pool what should have been communicated via a meeting at some point.  Calls out the jobs and requests people step up to fill them.   Also notes basket/raffle/etc plans.

A starting point for a request for donations.  Try to use the Tournament Coordinator to see if there's a master list of who in the community has donated to what, because the businesses tend to get quite a few tournament donation requests and some have expressed fatigue.
