How can you limit the number of games view-able when sending out a scorecast link?

Without deleting all your past scorecast games....

Is their a way to only make a league view-able?

You can use custom scoreboards to make only the games you want available. See the following link:

viewtopic.php?f=6&t=8064" onclick="window.open(this.href);return false;

If you have a team web site, you can also send a 'team' specific link . T=xxxxxxx in the line instead of c=deviceid.
