To pay via Pay Pal, follow the Dashboard link. There will be a link to pay via paypal. If you are not already logged into the site, you will be asked for your username and password.
To pay via check, just bring it with it on Saturday. If you haven’t already mailed it, there’s a good chance of it not being received and processed in time.
You can check your payment status on the Rosters page. There will be a note at the top that indicates the last time payment status was updated.
