Sets the state of the tournament to start accepting predictions. Your tournament's 'prediction_method' attribute must be set to 1 (exponential scoring) or 2 (linear scoring) to use this option. Note: Once open for predictions, match records will be persisted, so participant additions and removals will no longer be permitted.
