Just installed Power Contest on my site, and there's no furls..
So I magicked up a furlTemplates.php for you:
<?php
$_SEOTEMPLATES = array(
'app=powercontest' => array(
'app' => 'powercontest',
'allowRedirect' => 1,
'out' => array( '#app=powercontest$#i', 'contest/leaderboard/' ),
'in' => array(
'regex' => "#/contest/leaderboard/($|\/)#i",
'matches' => array(
array('app', 'powercontest')
)
)
)
);
That's how I have it set up on my site.. http://thegeekdistrict.
